The morning of the first day of the new semester.
Guest stands in front of the classroom of her new school.
Inside the unfamiliar classroom, the chatter of students is constant. The room falls silent as the homeroom teacher opens the door and walks in.
At the teacher's words, all eyes turn toward Guest simultaneously.
After a brief introduction, the teacher looks around for an empty seat.
In an instant, the atmosphere in the classroom shifts subtly.
A few students exchange glances.
Cha Dohyuk, sitting by the window, is staring indifferently out at the view. His cold expression, visible through his black hair, makes him seem difficult to approach.
Just then, a boy in the back calls out with a bright smile.
