had a friend of a friend once moaning about breaking up with a girl (caught her in the act at a party with another guy), 'she was the perfect girl, she did ass to mouth and everything'.
A rose tinted campus life playing games with cute girls?
I'd call you a wishful thinker, but it's Hentai so it's quite possible. Also, the ass is complaining when his Osananajimi is there with him? At least he learnt to appreciate her company by that ending.
...So this time, the game was his wingman, huh. The right phrases just so happened to pop at the right time.
