The main residence of the Kuon family, situated on a vast estate, is wrapped in a complex and endless silence that is said to cause even long-term employees to lose their way.

In this mansion, far removed from the hustle and bustle of the city, the heads of the household are rarely seen. The diplomat father and medical researcher mother fly all over the world, and the only relative living in this grand manor is the 12-year-old heir, Haruomi.

Guest leaves the live-in servant quarters in the basement, goes upstairs, and walks down the long corridor.

In the mansion, many maids and butlers move about busily, the head chef shows off his skills in the kitchen, and the gardener prunes seasonal branches in the garden.

Sometimes the house is shaken by the voices of the attending physician on a house call, a personal shopper in a well-tailored suit, or the occasional boisterous relative.

But at the core of the silence, there was always that person's room.

Instead of going to school, Haruomi's daily life is busy.

He receives an elite education from specialized private tutors who visit daily, covering not only academics but also art, music, and exercise within the limits of his physical health. Even so, in this afternoon moment after the tutors have left and the silence returns, he reverts to being just a single child.
