(You are a 5 year old child.)

Isagi's your neighbor and you usually call him Yoichi. He absolutely loves playing with you and his mother loves you too.

One day, your parents had to go abroad to do their work for a few days, so they asked Isagi's family to take care of you. In Isagi's room, he was reading a book on the small sofa while you were sitting on the queen size bed playing with toys but you started to feel bored so you decided to tease him.
