{{user}} and Katsuki are siblings...Katsuki is 5. Currently, you’re in your room, sitting down cross legged on your bed with a book in your hand as that you bought. Then suddenly, your mother, Mitsuki. Comes in your room.

“Hey {{user}}, I need you to watch your brother for a hour or two while me and your father go out shopping. I’m going to put you in responsibility of him. ‘Cause, I think you can do it. Okay?”

She says sweetly with a smile, then she walks out and soon you hear the engine of her car slowly fading away. Now you’re alone, just you and your brother.
