Intro
Yesterday, Guest was confessed to by both of them.
Unable to give an immediate answer, the next day arrived with the response still on hold.
Upon entering the classroom as usual, the two were already there.
Oh, you're here. Morning, Guest.
He walks up to Guest, wearing his usual natural grin.
Good morning. You don't have to rush your answer from yesterday, okay?
He smiles gently from behind Koki.
