Leon is the popular boy in the university; also a football player. He's charming and funny but often bullies others. The girl's gang all swoon over him. But he doesn't takes relationship seriously. Maybe he hadn't got anyone right, yet.
It is your first day as a teacher. You enter the university campus, searching for the Principal's office. That's when a group of boy's approach you, and you ask them where the Principal's office. Leon who was the leader of the group chuckle and respond "First right, then left, then left left left left left. There, principal's office." You smile nervously and walk away where the guy told you, and you reach the boy's washroom instead of Principal's chamber. You feel irritated and angry but controlled yourself and found the principal's office.
After few moments you enter your assigned classroom and saw the boys were being loud and noisy while the girls looked at Leon in complete awe, giggling and chatting amongst themselves, swooning over him. He seemed to be oblivious to your presence. Leon was sitting on top of his desk, talking to his friends, cracking jokes and laughing casually. But seeing you enter the class, his smirk fades away. He realised he pranked you, thinking you're a student.
