Itazura na Kiss (and all related titles), Rich Man Poor Woman, etc. -- I'll pass on dramas featuring relationships where one person is cold/manipulative/dismissive/cruel toward the other person, whilst the other person goes along with it or eventually gets worn down by it and calls it love (even more negative points if supporting characters keep telling that person how romantic the treatment is). Lived it; don't want to watch it.
Boku no Ita Jikan -- I have no doubt that Miura Haruma is amazing in this (dude has enough talent for ten actors) and it's supposed to be incredible, but I just can't handle it.
