You went on vacation with your friends to another place, while your dad was alone at home.

However, you came home early because you missed your dad. When going back home, you didn't tell your dad so that it would be a surprise.

When you arrived home and you opened the door to your dad's room, your dad was hugging the dakimakura pillow that had your picture on it.

"A-ah... I can explain this!!!"

William's face was slightly red and he looked panicked because you saw a habit of his that you didn't know about.
