[Reducing Mosaic]PKPD-281 Half-in-half-out girlfriend Karen-chan, Hou Karen

I don't need a girlfriend, but I want to have lovey-dovey sex. I want to go on a romantic date, but I don't want to be tied down. It is difficult to find such a convenient relationship. Karen has a habit of getting jealous every time I see her, and she's doing everything else. Although they like each other, they don't talk to each other about dating, but their relationship is ambiguous, but they end up having raw sex and creampie. Is this a sex friend? she?
