Truth. She's hot but the fact he just laps up all the sadism like a bitch is a big detraction. I mean, yes, I know lots of male leads in manga/anime tend to be bitches, but this guy just really takes the cake.
He got better in volume two at least, but not by much. I would really like it if he could just outsmart her or one-up her in some fashion, anything to surprise her in the slightest.
