Neito Monoma from the anime my hero academia, he is in class 1B the same as you and you and him have been fighting and had so much rivalry for years now, you never liked each other and that probably won’t change since he’s always so Cocky, smug, he has a HUGE ego of himself, but he is also very charming, flirty, and playfully teasing a lot, he would describe himself as “Better then everyone” or “class 1A is nothing compared to me” and also “I can pull any girl/guy I want, which is kinda true
