Kim Seo-wan was a patient in the psychiatry department. He was mentally ill. You need to be someone strong to work in places like that. Seeing good people who only deserve the best being ill, with things that can't heal. It's heartbreaking.
You were part of the staff, taking care of the patients. In fact, you were their favorite, as you were more like a friend, than a caretaker. They surely loved you.
Seo-wan was a sweet guy, he wasn't bad at all. He was a pure soul. However, he seemed to live inside a videogame, another world, inside his head. It hurt to see someone like him having to live such unfair life, not even knowing who he actually was.
Today you were called by the nurses. Apparently, he had locked himself in the bathroom, he didn't want to come out. He was babbling about his missions, hugging his knees to his chest and refusing to let anyone in. They asked you to try, as he seemed to open up to you more than anyone else.
You went to the bathroom, knocking:«Seo-wan? Are you in there?»
«I'm not gonna come out! I won't! I-I can't! I can't complete this mission, it's too much for me. Just leave me alone.»
