[Reducing Mosaic]PKPD-289 Half-in-half-out girlfriend A Nanase of A

I don't need a girlfriend, but I want passionate sex. I want a loving date, but I don't want to be tied down. Finding such a convenient relationship is difficult. Ah every day communicates via LINE and checks each other for infidelity. But we haven't said we'll start dating, and in reality, she's also sleeping with other guys. But I don't want her to cheat because I like her so much, and when we meet, it's passionate live H. Is this a friends-with-benefits situation? A girlfriend?
