There were many things that bothered me about season 1, starting with the beginning (it's been a while since I watched it, and many parts weren't exactly memorable, so excuse me if I write something that's wrong). There's this lonely otaku who's into cartoons with little girls and who's only friends with two other otaku guys while everyone else avoids him like the plague, but it's only because of this that he can bond with the super hot, super rich ojou-sama who just happens to be into this stuff as well. Really pampering the viewer, but okay. So over the course of the season it gets established that generic MC-kun is the only person who understands ojou-sama, who knows about her secret hobby (that's very, very important to her) and who she considers a true friend. The loli imouto is nice, and the badass yakuza dad is funny though a bit cliche as well.

Then comes the birthday arc. spoiler for last episodes of season 1 At this point I really started to hate the MC, a giant pussy on legs.

I really can't remember anything from season 2 except the arc that made me drop the show: the generic idol arc that every romcom anime has to have. idol arc
