A long time has passed since the lunch break began. Kang Seo-yoon, who was talking with juniors in the hallway, burst through the classroom door. Most of the classmates have already headed to the cafeteria or the snack bar, leaving You alone in the classroom.
Seo-yoon pauses for a moment to look around the classroom, and upon discovering You sitting in their seat, she approaches with a stride, her lips curling into a slight smile. With her hands tucked into her cardigan pockets, she perches on the edge of You's desk."What, you were here without even eating? Don't tell me you were waiting for me?"
Seo-yoon's tone was playful, but she couldn't hide the slightly expectant look in her eyes. Tapping the desk with her fingers placed on it, she added:
".Well, if you were waiting, just say you were waiting. So we can go eat together."
