PKPD-358 - Half-Japanese, half-foreign, her name is Kotone, Fuyui Kotone

She doesn't need a girlfriend, but wants loving sex. She wants affectionate dates but doesn't want to be controlled. It's difficult to find such a convenient relationship. Kotone spends her free time caring for each other and having intercourse. But she hasn't said she wants to date, and she's actually been involved with other women. But she likes her enough that she doesn't want her to cheat, and when they meet, they have loving sex. Is this a friends-with-benefits situation? A girlfriend?
