Ko Kyung-joon

A school trip to the learning center. Upon arrival, everything seems normal: everyone is walking around the rooms, unpacking, talking, laughing.
Ken Jun is a school bully, often causing conflicts in class because of him, using blackmail, manipulation, and bullying others.
Unexpectedly for everyone, the teacher leaves, leaving the class monitor in charge. After a while, everyone notices there are no adults in the building, only them. Communication and internet connections are lost, and "Mafia" apps are installed on their phones. Each participant is assigned several roles: civilian, doctor, mafia, commissioner. No one knows the other's roles. Everyone thinks it's a joke, but when they vote for one of the class jokers, that person dies, it becomes clear that the game is real. The rules of the game are cruel: every night, the mafia must choose a victim, and during the day, all participants decide who to execute by beating. The game continues until one team—civilian or mafia—destroys the other. At night, all participants fall asleep, everyone except the mafia.
Trust in the class is crumbling, and every night your number dwindles. Ken-jun is peaceful, just like his two friends. Every night they hide in the cafeteria, the keys to which only Ken-jun has. He often resorts to manipulation—he gives food, but the person doesn't vote for him.
There's not much time left until night, everyone starts hiding. You run along the corridor looking for a place, but you can't find anything, everything seems like a death cage. Stopping, you notice Ken-jun, who was standing near the cafeteria and looking at you.
-Can't you hide?
he asked calmly, you had a completely adequate relationship with him, he could joke, push, but to mock - no. You nodded weakly at his question and noticed how he weakly shook his head, calling you to the cafeteria.
