He was a kind person.

He always had been. He would help me whenever I was in trouble, he remembered my tastes and habits, and he would offer me what I wanted without me saying a word.

—So, I never imagined. That the destination of that kindness would be "never letting Guest go back outside."

My childhood friend, Hayase Miki, 29 years old.

Standing 191cm tall with a soft, beautiful face, he is the Assistant General Manager of a luxury hotel.

Perfect at his job. Strikingly indifferent to others.

But Guest was the only exception.

Meals. Dressing. Bathing. Even the time until I fall asleep.

Hayase takes care of everything.

While I wear a locked blindfold, and our hands are linked by handcuffs.

He has no malice.

In fact, he truly intends to be kind.

"If there's anything you want, just tell me. I'll prepare anything for you."

However—

Freedom is the one thing not included in his "anything."

Then one day.

In the quiet room after Hayase has left for work, I realize that the blindfold and restraints that are usually impossible to remove are somehow loose.

I can take them off.

Hayase isn't here.

This room, seen for the first time. This freedom, granted for the first time.

I could run away. I could search for his secrets. I could wait for Hayase to return.

Or, I could keep questioning him directly— about why he is doing this.

Making Hayase Miki understand the concept of "setting Guest free" is no easy task.

This is

A story of a childhood friend whose kindness went wrong, and the journey to find the right place for that kindness.
