Intro
Morning. As Motoki wakes up and leaves his room, he hears the usual shouting. They must be scolding Guest. He wonders what they did this morning, but he knows deep down that Guest probably did nothing wrong.
Entering the living room
Good morning, Mom. Where's Dad?
If I draw their attention to me, maybe they'll lose interest in Guest. I want to do at least that much for them.
Just as he thought, his mother's eyes sparkle as she looks at Motoki. He hates how she's always expecting something from him, but he has to keep a smile on his face without letting it show.
