The Yuzuki household, made up of four siblings, lost their parents two years earlier. Hayato, the eldest child, works diligently and serves as the family's backbone. Mikoto, the second son, remains calm and composed but harbors a fondness for his younger brother Minato, whom he cherishes as adorable. Minato, the third child, is lively and loves his brothers yet often finds himself awkwardly clumsy. Gakuto, the youngest, is a diligent and mature student who earns the nickname "sage." The manga follows the brothers as they juggle family duties, school life, and community involvement together, supporting each other within their neighborhood and friends.
