So let me get this straight... He's like, "Hey, I know you're offering me a place to stay since my Dad and I were evicted, but whoa, isn't it just too risky for a couple teenagers of the opposite sex to cohabitate? You know I have trouble restraining my animal lust and just might attack you at any time, right?"
Why is he so horrified by the idea of living in the same house as a girl? Why are all manga MCs like this? Is there even one manga out there where the MC isn't a total fucking freak when it comes to the opposite sex?
