Mystic Messenger has been around for a while, but it’s still one of the most popular otome games available today. Developer Cheritz regularly adds new content to the game, which keeps players coming back, but many of us still enjoy exploring the original routes provided in the base game. Here’s our guide on how to get every ending for the Sweet, Innocent Yoosung.

Save often and use your backups carefully to achieve all of these purposes more easily. Create backups that you can come back to when you get the ending you want.

Day 1 – 4

Begin the Yoosung route in the occasional story during days 1-4; you can do this by being wary of V, showing interest in the game, and being kind to him. Take an interest in his health and compliment his appearance. Be supportive and loving towards him to win as many of his green hearts as possible.

Good end

The good ending is the best possible ending you can get with Yoosung. To get this ending, you need to reach Day 11 with as many Yoosung Hearts as possible. You must also have at least 10 full mail chains. To maximize the number of hearts Yoosung earns, use the list of chat choices below.

Good end chat choices

Here are all of the choices you can use to secure the right ending.

Day 5

• What are you doing at night
• Yoosung feels a little different from now.
• What about the other members?
• Good memories.
• Yoosung seems happy too.
• How was he before?
• He’s just a second year student. He still has plenty of time.
• No. It’s not like that.
• It was good to talk to you, Seven ^^
• Did you see the photo sent by Seven?
• Jaehee must have been nervous lolo.
• Maybe Yoosung changed… because of Rika’s death?
• Golf clothing business? Why not invite them to the party?
• Did you brush your teeth after waking up?
• I should be in the picture this time, right? MDR
• Let’s take souvenir photos that we will never forget.
• Oh ~ I’m touched! haha
• I go.
• Zen, hello.
• I think Yoosung is actually a very talented person.
• I also like to see a relaxed Yoosung.
• Wish Yoosung good luck ^^
• Jaehee, did you have lunch?
• lololol You looked pretty in that picture, Jaehee.
• Are you not being too aggressive?
• Aren’t you changing the subject?
• Invite them to the party!

• What are you really doing?
• Alright Alright.
• Goodbye, Jaehee.
• Goodbye, Seven.
• Yoosung, did you have lunch?
• I did.
• Didn’t you just space out?
• Muah Muah
• Say what you want ^^
• I have the impression that he is preparing something in secret.
• There must be something that only you can do.
• Good luck! ^^
• Hello, Zen.
• What’s up?
• Oh no… does it hurt a lot?
• Don’t be so gloomy… Your health is more important.
• So… how about inviting this organization of doctors to the party?
• Good luck, Zen.
• Yoosung, how was the library?
• He must be better before the party.
• I also want to make a lot of memories with you, Yoosung.
• Yoosung, how were you today?

• This is to say that.
• Of course. We are different people.
• Yoosung is mine.
• We will have each other.
• Yoosung, think of it as fun. Everything will work.
• Jaehee, have you seen Yoosung?
• I’m glad Yoosung isn’t doing anything physical! He won’t be hurt.
• You must really like Zen.
• I think they will be helpful. Please tell them to contact me.
• Have a nice evening ~
• I am here, Yoosung
• I don’t believe it either lolol
• You lie.
• I can’t trust what Seven is saying.
• Yoosung will be able to defeat these bodyguards!
• Yoosung, you grew up!
• OMG …
• Yoosung, why don’t you try to learn how to make games?
• It’s a good idea.
• That’s a good plan, Yoosung.
• Serious Yoosung is cool.
• My pleasure.
• How is the cleaning going?
• Volunteering… was it fun?
• Rika seems to be a fantastic person.
• I am not Rika however.
• It must have been really hard …
• I am not the same person as Rika, but I want to be someone precious to you.
• Yoosung, you are so cute.
• I will go to bed.

Day 6

• Jaehee, you’re pretty late.
• I think Rika is a very big part of Yoosung’s life.
• I am worried too. Will get better soon.
• I will stay more awake.
• Good night, Jaehee.
• Yoosung ~ I missed you.
• Seven was there too ;;
• I don’t feel so good about it …
• What’s the point?
• It is therefore a trash can.
• I will support anything that makes Yoosung happy.
• You never told me before. Tell me haha
• Goodbye, Seven.
• I will always be with you ^^ Bye, Yoosung.
• Are you ready for the job?
• Cat shelter?
• Why not invite the folks from Cat Shelter to the party?
• Can Yoosung afford to raise a cat?
• Drug?
• It’s an insult lololol
• Yoosung will change from now on. Hope everyone encourages him ^^
• Goodbye ~
• Heya Zen.
• Why?
• So that’s the reason.
• I actually think it could be engineering.
• It looks nice. Let’s leave this option open.
• When do you get rid of the cast?
• Goodbye, Zen.
• Yoosung, have you seen the cat’s picture?
• I think Jumin should take care of that as well.
• Congratulations
• Since Jumin was born with a silver spoon in his mouth ~
• Jaehee, how could you …
• Drug.
• Yeah… Everyone’s so inconsiderate T_T
• Don’t be depressed, Yoosung. You can start talking about your classes from now on.
• Stop teasing Yoosung ~
• Yoosung, what are you going to have?
• Goodbye, Yoosung.
• Have you discovered what Yoosung specializes in?
• Find out everything else, but can’t do it?
• What school did you go to?
• lololol You are lying.
• Have you ever… raised a cat?
• Well. Let’s all hover and invite.
• I’m worried …
• …
• Zen, how practical?
• I know… I thought she was taking good care of herself.
• I agree.
• I think Yoosung will do a good job as well.
• Yes a little bit.
• Goodbye, Zen.
• Jaehee, are you going to take care of the cat?
• You have to respect Jaehee’s opinion.
• I don’t think that’s a good idea …
• I hope so.
• Thanks Jaehee.
• You are very busy.
• Jaehee, what about this?
• Can’t you log into the messaging and read the messages yourself?
• Bring guests for me ~
• Thanks for your concern, Jaehee.
• Yoosung, Jumin says he’ll give you a bottle of wine if you keep the cat.
• You can’t do anything if you want it enough lol. I want to see you raise the cat.
• lolol I’m sure Jumin will take good care of the kitten.
• But what is it?
• Its good! It’s a good idea.
• I’m blushing…
• I would love to meet him in person.
• Blushing …
• I can’t say anything because I don’t know what Rika looks like…
• Hmm ;; I am not Rika, Yoosung.
• Can’t he really tell me apart from Rika?
• Thanks for your interest anyway, Seven.
• Goodbye.
• Thanks for saying that.
• Jaehee! Hi.
• Won’t it make your ankle worse?
• You’re not talking about … the Hulky, are you?
• Let’s invite them to the party!
• I would like him to see me for who I am.
• Yoosung will change.
• Not interested in you lol
• Yeah… I think she could.
• My heart is already with Yoosung.
• Goodbye, both of you ~
• Yoosung, aren’t you sleeping?
• It’s natural. But you can’t confuse me with her …
• But I am not Rika.
• Even if it is true, I am not Rika.
• Is this Rika’s puppy?
• Good dreams, Yoosung.

Day 7

• You are still awake.
• I am the supermarket.
• Luciel, what kind of magic did you do?
• Forget the name and continue the story.
• Didn’t you fool the natives or something like that?
• At least you shouldn’t have given them the Nimtendo.
• … Let’s invite him !!
• Hope you take the spaceship and travel to dreamland …
• What do you think of its story?
• It was funny for me lolol
• Is anything wrong?
• There may be similarities, but we are different people …
• Thanks for your concern. Yoosung will change.
• Thanks Jaehee.
• Thanks for worrying, Jaehee.
• Yoosung, have you read the story of Seven? MDR
• I want to go on vacation too ~
• Yoosung, do you want to go camping or take a road trip?
• But I still think you should listen to the doctor.
• You tend to overload your body if you are overconfident, so be careful.
• If so … then it’s not really good ^^;
• Why would you feel bad?
• Than you … but honestly, I don’t feel so good.
• I think what Zen is trying to say is … it’s not good to overlap with someone else.
• Yoosung… Thanks for saying that.
• No, he couldn’t have ~
• Yoosung, I think you should calm down a bit.
• Yoosung, don’t be so offended.
• I understand what you are saying. It’s just that Yoosung needs more time to figure it out.
• Good luck, Zen. Yoosung will understand.
• Jaehee, aren’t you going to work?
• I like predictable.
• Well! (Secretary’s email)
• I admit she was special… but I don’t want him to ride me with someone else.
• Zen was in too much of a hurry.
• Thanks for your advice, Jaehee.
• Heya Seven.
• Gah !!! A monster that heals quickly!
• Zen was just trying to give some advice.
• Yeah, you were just curious.
• You are right.
• That’s the reason? I thought Jumin had done something very wrong.
• Well it’s not like Jumin is nice to Zen though lol
• Don’t think that’s the answer.
• You should have said it before lol
• Goodbye.
• Jaehee, do you think Yoosung would feel better now?
• Jaehee…? Are you OK?
• Go ahead.
• I want to heal him.
• Jaehee, you really care about him …
• Yes.
• Jaehee… I understand what you mean.
• Yoosung will understand what you are feeling. I will also help.
• Thanks for your advice, Jaehee.
• Yoosung, did you read… what Jaehee said?
• Let’s invite them. (Email of the winemaker)
• Jaehee is a really great person.
• What do you mean she lost someone important?
• Oh no… This is how she knows what it’s like to bury someone in your heart.
• Yoosung, in time you will be able to overcome the sadness of Rika’s death.
• I sincerely hope your scars heal soon. Comfort.
• People get over sadness in different ways.
• Thanks for your kind words, Jumin.
• Which part did you not understand?
• Thanks for saying that. I’m fine.
• Everything will be fine, Yoosung.
• Hey zen
• I found her a little too curious.
• What do you think will happen now?
• I think it will be nice.
• Hope the feast day is coming soon.
• Sleep well.
• Jaehee, I am here.
• Am I safe?
• What will happen to me?
• What happens if I leave?
• I would feel safe if Yoosung came.
• So you mean there’s a bomb here !?
• How can you laugh now ;;;?
• You should have told me in advance!
• Should I live here?
• I want to see Yoosung …
• I have no choice, do I? Haha.
• I trust you with my life, Seven …
• Yoosung… I’m scared.
• I think they had no choice but to put it there to protect the information.
• I will try to be calm too.
• Thank you for thinking so …
• You are also very precious to me.
• Okay. ^^
• Should I invite this group to the party?
• Calm down and go to bed. I’m not going anywhere.
• Jumin, I promised Yoosung that I would be his girlfriend lol
• How many years did it take you to have a girlfriend, Jumin?
• Jaehee is an innocent fan.
• I can not take it?
• All right, I’ll try to be calm.
• I’m… fine, right?
• I will try.

8th day

• I was invited out ^^
• Once we meet, we will officially be a couple.
• I don’t want to hear bad news anymore.
• A stalker !?
• You are so popular !!
• Your neighbors will report you.
• Goodbye, Zen.
• Jumin, I was asked to come out.
• Don’t make fun of him. It could be real.
• I also want to take days off ~.
• To be honest, I’m so nervous I can’t take it.
• Goodbye.
• Yoosung, did you sleep well?
• You are a winner.
• Hope nothing bad happens.
• Yoosung, are you going to take a break too?
• You’re so cute I want to give you a big hug, Yoosung.
• You look wonderful! The best!
• You will look too good with wings. What will I do?
• It will be resolved soon. Don’t worry too much.
• I feel so safe because of my baby ~
• Study hard today, honey ~
• Zen, have you seen the stalker again?
• It could really be a stalker. Be serious.
• I will think about it. Tell them to join me.
• Aren’t you moving to a better place?
• I don’t think anyone will be fired.
• Wow. So hard.
• Don’t be so rigid and help Jaehee.
• I want to grow a nice garden with Yoosung …
• Since everyone is so worried… I hope this is resolved quickly!
• Jaehee, Jumin, good luck on the reunion ~
• Please do something about the bomb.
• When will you come and remove the bomb?
• OMG. Do you want me to live with the bomb?
• I want to know exactly why V made this decision …
• What should I do if there is an intruder? (Alt selection 2)
• It’s hard…
• I’ll trust V’s decision for now.
• Please find a solution as soon as possible.
• Yoosung, the bomb problem is solved. You can relax now.
• I don’t think this will be resolved just by moving or hiring security.
• I understand your concern, Yoosung, but we all got ready for the party together. It’s also important.
• Did V lie to you all, Yoosung?
• Instead of letting the doubt rot… I think you should talk to V yourself.
• I hope… there was a legitimate reason he had no choice.
• Yoosung,… first, calm down.
• Nothing will be resolved by stirring.
• First off, I think Yoosung should talk to V.
• Thank you for your concern …
• Everything will be alright. ^^
• I will miss you, Yoosung.
• Is Yoosung okay?
• What kind of unresolved issues?
• What a pity…
• I miss Yoosung.
• Please do so.
• Seven … are you feeling good?
• Seven is so popular …
• But I don’t think V is a bad person.
• Would you like to contact V and have him talk to Yoosung?
• … Even that would be nice.
• I don’t want to know what Seven is doing …
• I think Yoosung will be back in about 2 hours.
• Jaehee, are you busy?
• Ya
• I think they are both doing their best to protect me.
• Jaehee, let’s talk again.
• Yoosung, you are here ~!
• Is there a chance that your phone will be bugged…?
• What is really going on?
• Wasn’t there enough evidence … about the cause of his death?
• This is why the RFP was so important to you …
• Yoosung… It must have been so hard for you.
• I don’t think it’s that easy to forget someone … V.
• Yoosung… I feel so bad.
• Please just answer some of Yoosung’s questions.
• Are you serious!?
• It was good at least.
• It attracted me with this app.
• Alright I understand.
• Having too many secrets will only fuel doubts, V.
• I don’t think you have bad intentions V… At least in my opinion.
• … Rika was mentally ill?
• Yoosung… are you okay?
• Calm.
• Seven… did you hear anything from Yoosung?
• Is it so shocking?
• Calm down ~!
• Do your best, Seven.
• Thank you. ^^
• Jumin, did you see V’s conversation with Yoosung?
• Please tell them to contact me ~!
• Seeing that he wants to break into the apartment, the information must be what he wants.
• Yeah. Why did they bother to lead me inside?
• It’s scary … I should change the password.
• This is because they want to come here themselves to gather the information.
• Maybe they wanted to use me… to get information for them?
• Jaehee, it’s impossible.
• I can’t believe you are starting to doubt me.
• I hope that at least the party is not affected by this situation.
• Do you think Jumin is trying to protect Jaehee right now?
• Everyone’s heart will be torn …
• Yes okay.
• Jumin, thank you for your words.
• Zen, did you come back to the stalker?
• For real!?
• It’s real… What are you going to do?
• Maybe this is the person who says, “The Jalapeno filling was quite spicy”.
• Zen, do you think you can sleep tonight?
• Yeah… I think it will be the safest place in the world. Take care of yourself.

Day 9

• Jaehee, how safe was you at Jumin’s place?
• What did the email say?
• He will get there safely.
• The cat is so cute …
• Zen, are you there?
• Isn’t Seven more dangerous than a stalker?
• Still no progress?
• Please … get me to safety. I begin.
• Health is most important, so take breaks in between.
• I hope everything is okay.
• Yoosung had no choice but to get angry. Because of V trying to hide everything.
• Do you think they are really strong?
• You should clean up a bit.
• It could come from an enemy.
• Seven, good luck!
• Yoosung ~ You have to have breakfast, okay?
• Nothing happened. Thanks for your concern.
• Don’t feel sad. It will be fine soon.
• Why didn’t you say anything?
• You’re not saying… Did Rika do that to V…?
• Yoosung… Are you okay?
• Isn’t that treatable …?
• Yoosung, are you okay?
• But still… It’s your eyes…
• Yoosung has just left! Do you think he’s okay?
• He didn’t want to hurt Yoosung because he cared so much about her.
• I’m sure you were a very good friend of V.
• Zen, did you know V hurt his eyes?
• How did you know he hurt his eyes?
• I feel like I’m surrounded by chaos… But it will all be over soon, right?
• I am so worried about Yoosung.
• I want to see V turn bright again.
• If everything V said is true … I’m sorry about V.
• It’s the best thing that can happen. It will happen.
• It’s so scary …
• Jaehee, you are amazing …
• He didn’t… pass out in his room, did he?
• Seven will take care of it.
• Did you find other potential guests?
• Please tell him to join me.
• Jaehee, I’m counting on you.
• Yoosung! Are you OK?
• Yes.
• Is that so? It seemed suspicious.
• Why Zen…?
• Yoosung, I think it would be better if you were in hiding too.
• I can protect you if you come here.
• Yes… This person brought me here.
• Since there is a bomb … I’m safe, right?
• Then I feel a little better.
• To know what they want … we need to find more information.
• A hiding…? Is the group a large organization or something?
• Seven, are you going alone !?
• Seven … It’s too dangerous. Think about it again.
• I’m worried, Seven …
• Yoosung… It’s too dangerous.
• Yoosung… thank you for standing up for me.
• Yoosung… you are precious to me too. So don’t make dangerous decisions.
• Yoosung is not a loser.
• If you want it so bad … I respect your opinion, Yoosung.
• Die!?
• Why work gloves?
• Come back safe and sound … I’ll wait.
• Yes I want to see you.
• I love you too, Yoosung.
• Yoosung left.
• Yoosung will succeed. I’m sure and certain.
• But do you trust V’s judgment, Jumin?
• You say I’m a good influence, right?
• What time does it start?
• Do you think he can come to the party?
• Stop messaging and actually talk to yourself.
• Were you childhood friends?
• So cold…
• Thanks, Jumin. Have a good evening.
• Seven and Yoosung… do you think they’ll be okay?
• We’ll know when Yoosung and Seven get back.
• Yoosung will be safe, right? (Alt Selection)
• Seven is like that too?
• I believe it will. Don’t worry too much, Zen.
• Invite him. The party will take place for sure.
• Okay. I’ll try to stay as calm as possible.
• Do you think Yoosung is okay…?
• It is a very difficult puzzle.
• Was there no one else who knew about Rika’s condition?
• Anything else besides that?
• Maybe he doesn’t want to hurt you in any way?
• V probably made the best decision for everyone.
• Rika is very beautiful.
• V will tell you everything one day …
• I’ll stay awake.
• V, will Yoosung be okay !?
• I know you’re sorry … but don’t I have the right to know our enemies? I feel like you’re just trying to hide everything.
• Are you sure?
• That’s what you came to say.
• Thanks for talking to me, V.

Day 10

• Jaehee, have you ever heard of Yoosung?
• There is nothing to add.
• They will come back.
• Thank you for telling me.
• Everything will be fine, Jaehee.
• Aren’t you two sleeping?
• Jumin is not sleeping?
• I really want Yoosung to come back soon…!
• Yoosung has changed so much it’s surprising
• I think Yoosung totally fell in love with me.
• Jumin has a lot of financial power, so he could have handled this one way or another …
• I feel like you would be a staunch believer, Jaehee.
• Let’s stop talking about it and wait for them to join us.
• Jaehee, don’t work too hard.
• Jumin, have you ever heard of them?
• Everyone must be safe.
• We don’t have much time… but can you still tell them to join me?
• It only makes sense if everyone is safe.
• Thanks for saying that. Sleep well, Jumin.
• Zen, haven’t you heard anything from Yoosung yet?
• I would have felt so alone if you had even accepted.
• Whose?
• Everything will be alright.
• Zen is too nervous.
• He is right.
• Not really surprising. Not really funny.
• Jumin, you’re funny in a different way.
• Would he really have it?
• I think you have a deep trust in each other.
• Okay. Thanks for your concern.
• Zen… are you okay?
• I wish they’d told us exactly what they were going to do …
• V said he would make sure they came back. I want to believe it.
• Yes… they will come back.
• Yoosung! You are back. I’m happy. I’m so glad!
• What happened?
• Just tell me, please?
• Anyway, I’m glad you’re safe …
• Can we see each other now?
• Rest for now. You have done so well.
• I love you…
• Okay. I am so glad you are back. Rest, Yoosung.
• I’m so glad Yoosung is safe!
• Did everything go well?
• Everyone is safe now, right?
• So they really wanted the information in this apartment?
• I can’t wait to finally meet Yoosung…!
• Seven looked truly lifeless.
• Sleep well, Jumin.
• I’m glad it all worked.
• We have to believe that everyone is safe now.
• All of this thanks to everyone for not giving up hope and waiting.
• If this party doesn’t work out, we can try again next time!
• I’m confident.
• A white shirt and jeans
• Hurry, Jaehee.
• I’m so excited…
• But I didn’t hear anything from Yoosung …
• Can’t believe I’m going to see Yoosung tomorrow. It sounds like a dream.

Day 11

• How long do I have to wait before going to the party?
• But why haven’t we heard from Yoosung?
• I want to see him!
• I think he’s exhausted his brain.
• I am an adult. It does not bother you.
• (all)

Normal end

To get this ending, you will need to have completed 10 emails or less. If you complete more than 10 chain emails, you will receive the correct ending. Follow the correct guide from end to very end, but only complete a few email chains to get this ending.

Bad ends

There are several bad endings in MM for each route. Maintaining a great relationship between your character and Yoosung is essential to prevent one of these bad endings from happening. Here are the criteria for causing a bad ending.

Bad story ending 1, days 5-7

To achieve this ending, you will have to convince Yoosung that you are like Rika. Consistently take his side and reinforce the similarities between your character and Rika every time he appears in the chat. Yoosung will end up saying that you feel “like a reincarnation of Rika” and the road to the bad ending will be set in stone for the rest of this part.

Bad story ending 2, days 7-9

To get this ending, continue on a normal route but don’t reinforce the similarities between the player and Rika. Take his side constantly and obsessively. After the hacker incident started on day 7, start blaming V for anything and everything. Eventually, Yoosung will ask you to meet him in Forest Park and the bad ending will begin.

Bad story ending 3, day 10

To achieve this ending, panic for your safety and persuade Yoosung to protect you. Yoosung will go with 707 to infiltrate Mint Eye and the bad ending will begin.

Bad relationship ending on 1, day 7

This ending will happen if you start the Yoosung Road during the prologue on days 1-4. After the prologue, if you don’t get enough hearts from Yoosung, he will face the player on day 7. This will start a visual novel with the bad relationship ending and will effectively end the road on day 7.

Bad relationship ending on the 2nd day 10

To get this ending, start the Yoosung Road and maintain a good relationship with him until Day 7. If you stop romanticizing Yoosung after Day 7, you will reach the visual novel on Day 10 where 707 and Yoosung infiltrate Mint Eye. The visual novel will have a different ending than normal or good roads.
