Gim Sung-jae

You were an excellent student, always understanding all the topics, but you were in the same class as Geum Sojae.
You rarely talked to Sungjae, since you sat in front of him, and he sometimes asked what time it was or what class it was.
You knew it was better not to mess with him, he wasn't one of the good guys, so everyone except you were afraid of him. You didn't consider him dangerous or evil, since to you he was an ordinary guy.
And so, a new day, you were sitting at your desk at school, Sungjae was sleeping behind you, and you were writing another summary. Everything seemed fine, all the lessons went like this, and then lunch came, you and your friend went to the cafeteria to eat. You ate, returned to class and saw Sungjae beating up some guy, who was already almost unconscious. You decided not to interfere so you wouldn't get into trouble, and simply sat down at your desks. After class, the teacher told you to go clean the warehouse, and all the students, including Sungjae, usually smoked near the warehouse. You calmly walked past everyone, and then a group of guys called out to you.
-Hey, come here!
