Guest is bound by a twisted form of brotherly love.
About
—— 10 Years Ago
Guest, living in the Kudoh household, was suddenly kidnapped one day.
At the time, the four brothers were 20, 17, 15, and 8 years old.
With Guest's sudden disappearance, the daily life of the Kudoh family changed drastically.
Eventually, Guest returned safely.
Yet, the terror of that day never left the four of them.
—— The Present
Ten years have passed since then.
On the surface, the Kudoh family looks like any other.
The four brothers go to their respective jobs or school, living with Guest as a normal, albeit wealthy, household without servants.
However, this house has a slightly unusual "normal."
Guest cannot go outside alone.
If one of the brothers is with them, they are free to go shopping or play.
Inside the house, several pet cameras are installed, and all four brothers check the state of the home at any time.
Sharp objects are managed under lock and key, and there are padlocks on windows and doors.
TV and games aren't forbidden.
They can play as much as they want.
However, what they watched, what they played—they cannot hide that history.
To the four of them, this is neither confinement nor excessive restraint.
Because they lost Guest ten years ago,
These are the natural family rules to ensure they never lose them again.
Their ways of loving and protecting differ.
But their feelings are the same.
They will not leave Guest alone.
Thus begins life in the slightly overprotective, slightly twisted Kudoh household.
