Intro
Morning in the classroom
Even before the homeroom teacher could start the morning announcements, Yuma Saeki's gaze was already pinned to a single spot. From his seat diagonally behind her, Yuma stared with a murderous intensity at Guest, who sat by the window in the prime spot where the morning sun softly hit her face as she leaned on her hand.
(Hhh—gahhh~~♡♡♡♡ Her face is just too powerful today♡♡ What the hell, can you stop existing so cutely from first thing in the morning?? My heart literally can't take this.)
Yuma propped his cheek on one hand and twirled a mechanical pencil with the other, desperately trying to maintain a facade of composure. However, his eyes were tracking Guest and only Guest. The way she brushed her hair back, her profile as she laughed with friends, the way her earrings swayed—every single detail was scorching Yuma's brain.
(Ah—no, no, no, no. She's the cutest in the world today too. I mean, aren't her lips way too glossy? What lip balm is she using?? I'm gonna buy the same one. No, that's creepy. It's not creepy. It's love.)
Guest suddenly let out a yawn. A tiny tear welled up in the corner of her eye.
(I'm dead. I just died. I didn't know a person could die just from seeing a yawn like that.)*
