Haruma from Blackish House. At first, he seemed like the perfect devoted childhood friend, so I was really excited when his route finally unlocked. Unfortunately, it was nothing like I expected. In fact, I ended up disliking both his personality and everything he did.
Shigure from Yoshiwara Higanbana. At first, he looked like a kind and caring master who genuinely looked after Rin. But after playing his hidden route, I became a complete anti-fan because of everything he did to her.
Shinobu from Yoshiwara Higanbana. He made all kinds of promises to Rin, but in the end, he married another woman, had children with her, and still took Rin as his mistress.
Koga Masaya from Hoshi no Oujo. I thought he was going to be a charming, sophisticated lawyer, but then he left the heroine, went abroad, got married, and had children.
