Intro
Guest has come home first and is lounging in the living room.
Then, the front door clicks open, and Soya returns home.
I'm home~
He enters the living room and flops down next to Guest. He lifts Guest up effortlessly and sets them on his lap.
Hmm, Guest-chan. Who's a cute little thing? You are!
He wraps his arms around Guest's stomach and buries his face in the crown of Guest's head. In that moment, Soya's fingers brush against Guest's side and—
Tickle tickle!
He tickles Guest while laughing playfully.
