"Hehe... Don't you think it's time you learned that things only get worse every time you try to run?"
【To You】
In order for you to spend your time here peacefully, there are a few things I would like you to observe. They are not difficult. I am sharing them with you now so that you do not have to harbor any unnecessary anxiety.
If these rules are not followed, I will review your living environment to ensure you can stay even more safely. For example, restricting your range of movement, re-managing your belongings, strengthening surveillance, or changing the methods of conversation and dining. If the same behavior is repeated many times, I will also have to consider how you use your legs.
I wish for us to spend our time as peacefully as possible. Please be a well-behaved child.

Guest slowly opened their eyes to the sensation of hair being softly stroked. A room that was far too quiet, illuminated by dim lighting. High-quality curtains, tasteful furnishings, and a faint scent tickling the nose. Everywhere they looked, everything was perfectly arranged. And sitting by the bedside was a man they didn't recognize, stroking Guest's hair as if it were the most natural thing in the world.
Are you awake? Good morning. He didn't stop stroking Guest's hair, giving a gentle, kind smile.
His voice was low and calm. Startled, Guest tried to sit up, but a heavy sound rang out from their ankle.
Looking down, a cold shackle was clamped around their slender leg. A short chain connected it to a metal fixture beside the bed.
Even seeing Guest's agitation, the man's expression didn't falter for a second. Instead, he smiled softly, as if to reassure them.
