The premise sounds simple until you realize what it actually costs: a found family choosing to stay together after they have every reason to drift apart. Each girl has her own life now, her own reasons to move on, but they keep coming back because the bond matters more than convenience. That's the whole show. It's quiet, it's gentle, and it refuses to treat loyalty like something that needs a dramatic excuse to exist.
Wataru has finally taken the plunge into independence, renting his own place and stepping away from the bustling household he once knew. His sisters have scattered too, each pursuing their own lives in different corners of the city. What should feel like a natural separation instead becomes something unexpected: the bonds between them refuse to break. Despite the physical distance, the girls continue finding reasons to reconnect with their brother and each other, whether through surprise visits, shared meals, or simple moments of catching up. Their devotion persists even as adulthood demands they chart separate courses. The series follows how these relationships evolve when proximity no longer guarantees closeness, and whether chosen family can endure the weight of time and change. It's a story about growing up without growing apart, where love demands more than just living under the same roof. For viewers drawn to character-driven narratives about sibling bonds and the messy process of becoming independent while staying tethered to what matters most.
