I just can't imagine them having a "normal", " Happy end" Relationship. It would work if it was a s&m manga relationship thing. It kinda feels like punching the girl he likes is his way to show his affection for her. I doubt that FL would like that
this guy has a chrush on her since he first saw her, and X years later still hasnt changed his asshole attidute towards her, and expects her to notice or even fall in love with him?
if it werent for the rivalry she would problably hate him even more then now.
