When I was an early teenager or preteen, can't remember which, I watched some anime called Love Hina, and holy shit, is it terrible. Both the main character's girlfriend constantly punching him (because domestic violence is so funny when it's female-on-male, right?) and the whole "Oops, I accidentally just sexually harassed you!" That's just what I remember. There's probably a lot more worse shit about it.
isnt love hina a harem type anime with tons of "fan service" and slapstick?
and the loser dude lives with all these girls in a house and cant get any, but he keeps trying. and the girls somehow never kick him out, despite him perving on them constantly and some of the girls punching him all the time.
Keitarou and his childhood sweetheart make a promise to be accepted at and to meet each other at the prestigious Tokyo University (Toudai) before she moved out of his life. About a decade later, Keitarou has become an artist and a daydreamer, having ranked 27th from the last in the national practice exam. When his grandmother leaves the all-girls dormitory, he becomes the residential manager and soon meets up with two Toudai applicants who may have been that sweetheart, since he has forgotten her name. And then there are the other tenants like young Shinobu who was in despair until Keitarou helped her, Motoko the swords master who sees men as evil distractions, Kaolla Su the genius child inventor and the sneaky Kitsune.
Also 4/5 of the girls in the show are minors. To include the primary love interest (although at least she's 17 to MC's 19). But he does "accidentally" perv on some of the younger girls, who are like 12/13.
