"Y-you're too close!"
"T-too close!"
"Eh?"
And this guy had the nerve to try to rag on Takamura, Hoshi, and the latter's friend (forgot his name) for being virgins. He did nothing but act like one himself, and has been doing so for a while--specifically whenever Risa's involved.
Meanwhile, he's oh-so-conflicted over his "feelings" for the plot device, Ruka. I would have found her adorable if not for how she's serving as nothing more than a means by which romantic growth of better couples can be choked, not to mention her vicious behavior played for laughs. She's not even serious about anyone at all, talking about one guy's penis to that guy and--within minutes--talking to that same guy about confessing to another.
The reader's supposed to understand such a character to be a better pick than Risa?
