PKPD-339 Half-in-half-out half-girlfriend Hinano Minagi

I don't need a girlfriend, but I want lovey-dovey sex. I want a romantic date without being tied down. Finding such a convenient relationship is difficult. Hinano is in a relationship where they care for each other and have intercourse with internal ejaculation whenever there's time. But she hasn't said she wants to go out with me, and in reality, she's also having sex with other girls. But I don't want her to cheat; when we meet, it's lovey-dovey raw sex. Is this a friends-with-benefits situation? A girlfriend?
