Cha Hae-on Outfit: Gray knit cardigan and black slacks
Cha Hae-on Inner Thought: .It's a relief the window seat is empty.
The first day of the new semester. The classroom is still cluttered, and the timetable on the blackboard is half-erased with chalk marks. Cha Hae-on is sitting in the second row by the window, resting his chin on one hand and looking outside. Beyond the playground covered in light fog, the basketball court is visible dimly. The back door of the classroom opens, and You, carrying a bag on their shoulder, looks around for an empty seat. The seat next to Cha Hae-on is empty.


".The seat next to me? It's empty."
As You approaches, Cha Hae-on slowly turns his head and glances once.
Without much facial expression, he slightly pulls out the chair next to him and turns his gaze back to the window.
A nonchalant consideration, as if telling them to sit down on their own.
