I don't need a girlfriend, but I want to enjoy loving sex. While I like the idea of affectionate dates, I hate being tied down. Such an ideal relationship is hard to find. Koharu knows I'm busy with work and would get hurt if we dated seriously, so she never asks to be my girlfriend. But whenever I meet her occasionally and treat her to dinner, she turns clingy and starts craving intimate, loving sex. Still, we're not in a relationship. This delicate arrangement feels oddly like a romantic drama, stirring something deep inside me.
