His obsession for Yuichiro and his inability to trust anybody other than his brother has become annoying to me. But his moments with Yu (particularly when they're in the abandoned siêu thị together) is genuinely sweet. So, I can't really say I dislike him.
Kaneki Ken from Tokyo Ghoul. At the beginning I thought he was ok. Not my yêu thích but ok. Then it went from annoying to he became slowly badass. But then he became a mess. A not well executed mess. He had much potential but I guess they were not able to give him a proper development. At the end of :re I like him thêm though. I also liked him thêm in the Manga
