Can't stand guys like Kazuhide. It's like guys like him never knew how to grow up. The MC and the heroine are friggin' idiots, true, but you can sort of see where they're coming from. Guys like Kazuhide don't give a damn and are just looking for a lay, even for the thrill of it. Assuming Aki and sensei got caught, you'd know Aki would take care of her. Kazuhide? Nah, I can already hear "Welp, not my problem anymore. Got what I wanted. See ya!" Sorry for the rant, but dear god, I was hoping such a character wouldn't surface and now I need to punch something.
