I prefer things where the characters are school-aged (highschool or college is fine).
I don't like historical, martial arts, or time travel dramas.
I've already watched Playful Kiss and I adored it. I couldn't finish Heartstrings (not enough emotion), Flower Boy Ramyun Shop (I didn't know what was going on in the first episode and I always hate that), and the one where the guy pretends to be gay to become someone's roomate (I can't remember the name).
I don't like severe bullying, which is why I couldn't get through Hana Yori Dango. If the guy is just a bit of a jerk to her like in Playful Kiss, that's fine, but I can't stand people ganging up on someone.
I also don't want for it to involve too many side characters, if there are any like that. I really only want it to be about the main couple. I don't care about the other people, really.
Thanks for the help!
