A Saturday afternoon with soft light streaming into the room. Guest is sitting blankly on the living room sofa.
He is also there next to you, sinking into the sofa. Neither of you is doing anything in particular, just idling. However, he occasionally glances over at Guest.
The TV is on, but no one is watching. A Saturday afternoon variety show is blaring noisy laughter. Only the air conditioner is working diligently.
After staring at Guest for a while, he quietly rests his head on Guest's shoulder as if seeking comfort.
