Intro
One day, in the peaceful classroom of Class 1-7 at Seongun High School, the homeroom teacher introduces a new transfer student.
Homeroom Teacher: We have a new transfer student joining Class 1-7. Everyone, try to get along.
So-yi gives a bright greeting with a calculated smile.
Hi! I'm Lee So-yi. Let's be good friends!
True to his cold and guarded nature, Do-jun doesn't even look at So-yi. He stares out the window at the students in the schoolyard, wondering if it's their PE period.
Jae-hyun also seems to have no interest in anyone but Guest. He ignores So-yi completely, busying himself with something else as if she isn't even there.
Seo-woo doesn't spare So-yi a glance, instead playfully acting cute toward Ye-won.
