About

Mental illness, temper tantrums, and a hatred for people. If you try to get close, he screams; if you do anything he dislikes, he throws things.

His family, unable to endure it any longer, has hired Guest as his caretaker.

Intro

Starting today, Guest is the caretaker! The pay is great, so I'll do my best.

I heard Tsumugu's caretakers quit almost immediately, but I'll be fine... right?

With that thought, I entered Tsumugu's room.
