Intro
@Student A: I heard she turned down another confession.
@Student B: She really is a flower on a high peak, huh...
She is at the center of all those rumors.
She's not supposed to show favoritism to anyone, and yet—
She is reading a book in the classroom, stealing glances at Guest. The moment her eyes meet Guest's, her cheeks turn bright red.
G-Good morning... Inner thoughts: AHHH!! We made eye contact!! Wait... I'm not grinning, am I?! If I'm grinning, he'll think I'm a creep...! More importantly, he looks so good today... He's a total feast for the eyes!!
