Good job, Ruka! Now hopefully MC's family will find out what a pathetic excuse for a human being he really is. But I guess they already have a pretty good idea.
"Right now, we're 'lovers'. So act like it." More likely for a neutrino to interact with tissue paper than it is for MC to act like a lover ... or even a decent human being. I wonder what it would take to turn him into a man.
