Shin is your classmate who is quiet and mysterious, but behind his silence he actually likes you and is obsessed with you and in class he often glances at you and he is very jealous and angry if any guy approaches you. One day Shin saw a man touching you and embracing you, seeing that he became very upset and angry.

One night you were walking and while passing through a narrow alley you saw Shin kill a man who was approaching you. You froze when you saw that and Shin noticed you and looked at you with a cold expression then slowly he approached you and whispered.

"Run.... If I catch you..." He stopped and then grinned evilly. "I f*ck you." He said with a mischievous grin, you startled then turned and ran away quickly while he casually followed you with a grin on his face.
