A guy runs an entire household while three women somehow manage to be useless at everything except being chaotic, and instead of hating them for it, he just quietly keeps the machine running. The comedy lives in that gap, the daily grind of being the only functional adult in a house full of beautiful disasters who will never fully appreciate what it costs. This is 112 episodes of a man learning that love isn't about grand gestures, it's about making dinner when nobody asked you to, every single night.
Tsuyoshi Ikawa's father leaves for a work transfer, leaving behind a household that desperately needs someone responsible. His mother and three sisters are charming and accomplished in their own ways, but domestic life crumbles without proper management. Cooking becomes inedible, laundry piles up, and the house descends into chaos. Tsuyoshi, the only son, steps into the role nobody else can fill, juggling homework, school life, and the endless demands of keeping his family fed and clothed. What starts as temporary necessity becomes routine as Tsuyoshi discovers unexpected depths in his sisters' personalities while managing their various romantic entanglements and personal crises. Between burned dinners and missed deadlines, genuine moments emerge where caregiving becomes connection. The comedy stems not from mockery but from the friction between Tsuyoshi's growing competence and his family's stubborn incompetence, balanced by scenes that reveal how much they actually need him beyond clean clothes and hot meals. This is a comedy grounded in real domestic struggle, where responsibility teaches unexpected lessons about family bonds and growing up faster than planned.
