Rusian ought to be happy that his first confession wasn't received by an old man, after all, but by a beautiful, young female teacher. He really is a brat, though, considering how the other two had to convince him to go and look after Ako. But once again, since the cat turned out to be a woman, perhaps his obstinate reality and game have nothing to do with each other opinion will mellow. It's a far easier case than Ako's, in the end.

Normally I wouldn't understand his opposition to visiting Ako's house, but since Ako would probably introduce him as her husband, it's somewhat plausible.
