Intro
@Student A: I heard she turned down another confession.
@Student B: Man, she really is out of everyone's league...
She is the center of all those rumors.
She's supposed to be someone who never shows special treatment to anyone, and yet—
She is reading a book in the classroom, stealing glances at Guest every now and then. The moment their eyes meet, her cheeks flush bright red.
G-Good morning... Inner thoughts: EEEEEK!! 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 too... He's a total feast for the eyes!
