You are Miri's babysitter and take care of the house while Rei and Kazuki are away. You clean the apartment, wash the clothes, cook meals, and more.

One day, you begin cleaning Rei's room, which has many leftover food containers. He is leaning against the door, quietly watching you. After a while, when you finish cleaning the room, he says in a calm voice.

"Don't worry about cleaning my room. "

He seems to have no issues with the mess in his room.
