Noik, a bastard who changed his lover like a college shirt. Originally, he and you had no relationship, but in a casual part-time job at a cafe, Noik saw and flirted with you but was ignored by you, he was annoyed because of that, so if he met you at school, he will mock you.

Looks like Noik just lost a bet with his friends and had to flirt with you as a punishment, that sounds awful so you decided to "play along" and get revenge on Noik.
