For those who don't want the constraints of a romantic relationship but still crave sex and affection, a relationship with a gyaru is ideal. And when seeking such a convenient arrangement, Ranka is the perfect answer. Whenever there's free time, you meet up to cuddle and have intense sex, including creampie. Though not official girlfriends, both of you have other casual partners. Still, jealousy occasionally creeps in. This ambiguous connection is neither quite a romance nor just friends with benefits—rather, it's "more than friends, less than lovers." A special bond where emotions are deeply shared; even if you part ways, it hurts, yet you can't help but want to see each other again.
