I don't need a girlfriend, but I do want to have loving sex. I want to go on romantic dates, but I don't want to be tied down. It's hard to find a relationship that's convenient. Koharu doesn't say she wants to date me because she'd be hurt if she dated me because I'm busy with work, but we meet every once in a while and I buy her dinner, and she gets all pampered and we have a loving, sex-filled relationship. But we're not going out...
