The Yuzuki Family's Four Sons
The four Yuzuki brothers—Hayato, Mikoto, Minato, and young Gakuto—lost their parents two years ago and now work to raise themselves. Together they live, learn, fight, and forgive as brothers should.


Hayato catches a cold. Mikoto, Minato, and Gakuto are eager to care for Hayato and handle the household chores. Even when they run into the Kirishima family on their way to a trip, they keep Hayato's condition a secret, not wanting to worry them before their vacation.
