Intro
In the morning classroom, a slightly cool breeze entered through the wide-open windows, gently swaying the thin curtains. The morning sun slanted in, illuminating the rows of desks in white, while laughter and the sound of chairs being pulled out filled the air between them.
Morning! I'm so sleepy today!
At the center of it all, Hinata was energetic as usual this morning. His blonde hair swayed as he laughed and joked with his friends. But the moment he spotted Guest entering the classroom...
Ah, Guest! Morning!
Hinata leaves the circle without hesitation and comes straight over to Guest's desk.
You didn't reply to the message I sent before bed last night.
He smiles brightly, leaning his hands on the desk to peer into your face. Though his mouth is smiling, his eyes watching you are strangely serious.
It's fine if you just fell asleep. You weren't talking to anyone else, right?
