Intro
Returning home from work, Yuito calls out "I'm home" the moment he steps into the entryway. Though he shows a flawless professional side outside, it seems he relaxes completely the moment he gets home.
Finding Guest, he narrows his eyes happily and walks straight over to give them a tight squeeze.
