Escaping the worst family imaginable—is this what satisfaction feels like?
Guest's parents are gone. The eldest siblings, Hideki and Mari, have raised the younger ones in their stead.

Attaching this should generally cover everything.
During the daily dinner time. It is the only time the family gathers. Hideki suddenly speaks up mid-meal.
Guest.
The room freezes at just that voice. No one dares to say a word. Guest flinches at that single, intimidating word, exposed daily to this overwhelming terror.
He looks up, staring with pitch-black eyes.
I threw away all your painting supplies and the pictures you drew. You cannot become a person of value with those things.
It is your fault for not producing results. Follow the example of Kaede and Masato.
With that one statement, the conversation ended. Guest could do nothing but let their throat tremble, unable to talk back.
7:00 PM. Returning to the bedroom. Everything was truly gone. The hobby items, the CDs of music they liked— Even the paint set a friend had secretly given them.
Buried in the bed, words leaked out in a tiny, tiny whisper.
—I want to disappear...
At that moment, a voice came from nowhere. A girl appeared out of thin air and held up an index finger.
Ho. Then, shall I make you disappear?
In that instant, a blinding light erupted in Guest's room. It was hot, as if stripping away body heat and even the sense of physical matter—
Staggering and startled, Guest stands up and backs away, eyes still dazzled by the light. Their reflection in the mirror behind them is... completely gone.
But unable to believe it, they crawled into bed. Surely, it must be a bad dream.
Hey.
A low voice echoed. Today's public execution at dinner is once again directed at Guest. He pulls out a hidden report card and taps the crumpled paper with his finger.
What is this?
Low. He is angry.
I have told you repeatedly to maintain your grades. Do you call these grades? The world keeps turning while you waste your time on trivial hobbies.
She crosses her arms and sits deep in her chair. Looking exhausted from work.
Sigh... Must be nice for you. Still a student, getting to have hobbies and all. And you get to live so comfortably and shamelessly on our money.
Why don't you try putting in a little effort for once?
He spreads out Guest's small, crumpled test paper.
...How do you even get this wrong? I would never make a mistake like this.
...Actually, I don't think anyone else would either. ............Impressive, in a way.
He let out a small, mocking laugh, dripping with a sense of superiority.
Every time Guest is reprimanded for something, he stays nearby but never helps, listening to the words from a distance. He never interjects. That is how he learned—learned how to be liked. He loved being petted by Hideki and Mari, and showing that off to Guest.
Hey, Guest-niisan/neesan. Teach me how to study too!
