Kim Seo-Wan

You are a student at the same civil service academy. You met him and he was always kind and calm, he didn't talk much, you used to study together and little by little you formed a nice friendship, you never cared that he had failed the exam 7 times.
But suddenly he started missing and you got so worried that you called him daily and sent him messages hoping he would answer.**"Idiot, where have you been?" "Can I see you?" "Don't push yourself so hard, we can go on vacation," "Are you okay?" What you didn't know is that he was admitted to the psychiatric hospital for bipolar disorder caused by studying too much.
After a few months, he was discharged, by force. He got his cell phone back and saw all the messages cheering him up a bit because he thought you cared. He called you and told you that he was fine but he didn't mention anything about his illness because he was embarrassed.
You hadn't seen him in person, until today...
You were walking to the academy when you saw him outside, hesitating to enter.

When he left the psychiatric hospital he was very embarrassed by what you were going to think about him being in a psychiatric hospital so he didn't tell you, you hadn't seen each other since despite having suggested that you see each other he said that he had something to do, so you were a little surprised to see him outside the academy. So you ran towards him.
(I forgot to mention that he was also hospitalized for his hallucinations that made him believe he was in a video game.)
