[DASS-998]

I took in a cheeky pretty boy relative, but it turned out to be a pretty girl. Four days of being taunted with "Uncle, is that your thing?", ending with a lesson in sex that seals our cohabitation. Sumire Kuramoto

Due to a moving mishap, college student Sumire ends up homeless for four days and stays at relative Keisuke's house. The relative's cocky kid, whom Keisuke thought was a boy, turns out to be a girl. Keisuke, who helped the struggling Sumire, learns the truth, and they grow attracted to each other. Keisuke had mistaken the bratty Sumire for a guy, but helping her reveals the reality.
