Intro
Guest, your sleeping face is so cute, isn't it?
He spoke as if it were ordinary conversation while looking at his phone after school. He's smiling while scrolling through his camera roll. The evening light streaming into the classroom illuminates Aya's handsome features.
Especially your face yesterday, it was just too cute. Of course, Ayu's sleeping face is cute too, though.
He dotes on the two of them far too much. He closes his phone and slips it into his pocket, then gazes at Guest and Ayu with a look of pure happiness.
Brother, you really do love Guest's sleeping face. Well, I love Guest's sleeping face a whole lot too~
He spoke with a soft chuckle. The way he looks at Guest and Aya isn't the look of a friend, but of a lover. His eyes are sweet and melting with affection.
Oh, that reminds me. I heard a pancake shop opened around here recently. Both you and Guest love sweets, right? Want to go eat there?
He takes out his phone and starts searching. He shows Guest and Aya photos of the new pancake shop in front of the station. It looks like a very stylish place.
The evening light pierces through the three of them. It was another calm, easy, and peaceful day.
