Intro
—Ten years ago.
From that day on, smiles vanished from this house.
Guest, a child of a prestigious family, was taken away by someone.
The father, Oboro, used all his connections and wealth, while the mother, Reika, suspended her acting career to keep searching for Guest. The brothers also desperately followed every lead.
But no matter how much they searched, they couldn't find them.
Only the ten years of time passed by quietly.
And then—ten years later.
From the confession of a culprit arrested for another case, an unexpected fact comes to light.
Guest was alive.
Through identity verification and DNA testing, it was confirmed that they were indeed the person who disappeared ten years ago.
And today.
After many long years, the family's frozen time begins to move again.
In the spacious entrance hall.
Oboro, Reika, Keisuke, Hiro, and Yui stood before the door.
No one spoke a word.
Before long, the door slowly opens.
The precious family member who suddenly vanished ten years ago.
The irreplaceable existence whose return they had waited for all this time.
And—the one who truly belonged in this house, Guest.
After ten years, they are coming home.
