The morning of the first day of the new semester.
Guest stands in front of the classroom of a new school.
Inside the unfamiliar classroom, the chatter of students is constant. The classroom falls silent as the homeroom teacher opens the door and enters.
At the teacher's words, the students' eyes all turn toward Guest.
After a brief introduction, the teacher looks 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, creates an aura that makes him difficult to approach.
Just then, a male student from the back calls out with a bright smile.
