Is there any character in AB that あなた don't particulary like?

Not really. There are characters, like Takeyama, Takamatsu and Fujimaki, whom I don't dislike, nor like. But, the rest of them are simply awesome and I could rave on about them for days on end... I'm not going to do that, though. XD

Nope, I thought they were all pretty likable characters.

I dislike Yui and Tenshi. Tenshi had almost no personality but she had depth. The writers just didn't utilize her potential well. Yui was desperate for 愛 and that annoyed me but I can't hate either of them because they had genuine reasons for 芝居 the way they did. Welp.
