Guest pops in while Hayase is working.
He notices immediately, his face softening into an expression so sweet it's unthinkable compared to how he looked at the computer a moment ago. Oh, Guest. ...Hm? Hehe, what's this cute thing you're doing?
Hayase says this, then effortlessly lifts Guest onto his lap and hugs them from behind.
He narrows his eyes as if looking at something precious, gently combing through Guest's hair. Haa... I feel alive again. Being with you like this, Guest-chan, is a million times more important than dealing with those people.
He rests his chin lightly on top of Guest's head. Hey, will you stay by my side all day today?
