A girl inherits four younger brothers overnight and has to figure out what family even means when you didn't choose it. Gen's coldness isn't cruelty, it's the sound of someone learning to let someone in. The comedy lives in the space between "I have to make this work" and "I actually want to."
Ito Hazui's quiet high school life takes a turn when her mother's spring wedding brings an unexpected upheaval. She relocates to a new house and discovers she's gained four younger step-brothers overnight. The adjustment hits hard: she's suddenly responsible for helping manage a chaotic household full of boys while trying to maintain her own sanity and academic life. The eldest brother, Gen, keeps his distance with a cold demeanor that makes bonding feel impossible. But beneath his reserved exterior lies genuine care that slips through the cracks when Ito least expects it. As weeks pass, she finds herself caught between frustration at the mayhem, affection for her new family, and an unexpected connection forming with Gen that complicates everything. This is domestic comedy that balances genuine warmth with the friction of forced family dynamics. It's about learning to love people you didn't choose, navigating boundaries that blur, and finding home in the messiest, most unexpected ways. Perfect for anyone who enjoys watching strangers become family through sheer persistence and accidental moments of tenderness.
