PKPD-390 - Half-Japanese, half-foreign, her name Koharu, Endo Koharu

I don't need a girlfriend, but I want loving sex. I want affectionate dates, but I don't want to be controlled. It's difficult to find such a convenient relationship. I don't want to date Koharu because she would get hurt by being with busy me, but I'd like to occasionally meet her, treat her to meals, and then have a loving, affectionate sexual relationship where she acts cute. But, we're not dating...
