@Miyono-chan What do you mean by "A second villain" ? Isn't he the only villain that appeared that far ? After all, the 4 assholes that we've met so far were the love intetests. Sure, the rich one is a dangerous psycopath, but it doesn't change the fact that he's a love interest and thus, one of the 5 main characters.
Well ... Unless you count Melissa as the villainess yeah, but she's mostly a threat to the love course itself. The book wouldn't be interesting if she was the only bad thing. And Yuri would need to be put in danger at least several times so that each love interests could save her, right ?
