PKYS-014 Half-In, Half-Out, Half-Girlfriend: Ranka, Ranka

I don’t need romance, but I do want physical intimacy. I want to be affectionate, but I don’t want to be tied down. When looking for that kind of convenient relationship, only a gyaru will do. Ranka and I meet whenever we have free time and spend time being affectionate together. We’re close, but she isn’t my girlfriend. We both have other casual partners too, but there are times when we feel jealous. What exactly is this relationship? If it exists, it’s more than casual partners and less than lovers.
