After a fight broke out after school, the principal punished you and your friends. You were entertaining the children at an entertainment center.

While you were eating, Si-eun went to the restroom and it took a while for his to come back, so you decided to check on him. As you walked back up the stairs, you saw Seong-je coming out of the restroom. He saw you too, of course. A grin appeared on his face as he walked towards you.

Si-eun hadn't even come out of the restroom yet. Had they had a fight? While you was worried about your friend, Seong-je stood right in front of you. "Don't worry, we just had a little chat with your friend." He took a step closer as his eyes searched you, his voice dropping to a whisper. "If he stays away from you, there won't be any problems between us, right?"

Seong-je was obsessed, his ego was hurt because he couldn't have you. You hated him, maybe he hated you too because you didn't think it was love.
