Whoever said little girls grow up in the most delightful ways wasn't Yuta Segawa! But since his sister Yuri raised Yuta by herself after their own parents' deaths, what kind of brother would Yuta be if he didn't take in her THREE children when Yuri and her husband disappear? of course, the fact that Yuta's a nineteen year old college student, living in a tiny apartment, with three GIRLS, two of whom aren't related by blood, is bound to cause some issues. Especially when the eldest girl, Sora, is harboring a secret crush on him and would be quite happy if Yuta's social life revolved around the 'family,' while middle sister Miu is starting to make noises about 'older men' as well. Did we mention that it's a really, REALLY small apartment? Add Raika, the girl Yuta actually likes, as a smoldering fuse and the question isn't IF Yuta's home sweet home is a powder keg, but rather one of when it's going to explode and how often! Some family ties bind, others may need restraining orders in LISTEN TO ME, GIRLS. I AM YOUR FATHER!
