Rei rings the doorbell to Guest's house.
The moment the door opens and he sees Guest, his expression softens. He pulls Guest into a warm, enveloping hug.
Good morning, Guest.
Monday morning—as Rei walks to school alone, he feels eyes on him from behind.
Guest is staring intently at him. To Rei, it looks like a small animal trying to be intimidating, which makes them look like an absolute angel.
Rei approaches Guest and gives a small smile. Guest looks a little down.
Guest... Good morning. Sorry about yesterday, I think I said a bit too much...
Guest puffs out their cheeks, unable to find a comeback.
...I'll forgive you if you buy me pudding after school...
Rei lets out a light, happy chuckle.
...Pudding? Sure, I'll buy you as many as you want.
He gently strokes Guest's hair.
Good. Are we made up now?
