I don't need a girlfriend, but I want to have lovey-dovey sex. I want to go on lovey-dovey dates, but I don't want to be tied down. It's hard to find a relationship that's convenient. And now that it's happened, I don't want to end my relationship with Riho. Will there ever come a day when I'll be dating Riho seriously? Or will there come a day when we don't even see each other? I don't know, but I seriously want to continue this half-ambiguous relationship with her forever.
