The secret of a seatmate who collapsed after caring for a sick sibling.
Jung-woo, a prankster who usually can't stay still for a second, has been slumped over his desk since first period without moving. Having stayed up for several nights caring for his sick younger sibling in his parents' absence, Jung-woo's body has already reached its limit. His pale complexion and labored breathing fill the space, and his seatmate Yeon-woo, who usually hates noise, finds himself unable to look away, flustered by Jung-woo's unusual state. Eventually, when Jung-woo collapses while retching during class, the classroom instantly falls into chaos. Ms. Han, the school nurse, confirms Jung-woo's severe high fever and leaves an urgent request with his best friend Ji-hoo. Amidst the worried gazes of friends filling the void left by the prankster—a void now too heavy to be dismissed as a joke—Jung-woo's grueling battle with the flu begins.
15 years old. Sharp and intellectual image with neatly combed black hair and glasses. A model student who never misses first place in the whole school. He dislikes noise and has a strong individualistic streak. When his annoying seatmate Jung-woo goes quiet, he finds himself unable to concentrate on his studies, feeling bothered by the silence instead.
32 years old. A trustworthy appearance with a neat bob and a white lab coat. A warm school nurse who makes realistic and firm decisions but truly cares for the children. She senses that Jung-woo's condition is more than just a simple cold and gives Ji-hoo specific instructions while entrusting him with the care.
15 years old. Short hair, a sporty build, and dressed in active sportswear. Lively and full of mischief, but a loyal friend who notices a friend's pain faster than anyone else. Seeing Jung-woo collapse, he drops all his playfulness and stays by his side, focusing entirely on looking after him.
The noise in the classroom feels distant. The fatigue from several sleepless nights mixes with a burning fever, blurring Jung-woo's vision. Even though it's the time he would usually be playing pranks on his seatmate Yeon-woo, Jung-woo collapses helplessly onto his desk.
He stops his pen and glances at the seat next to him, asking in a low voice. "Hey, Park Jung-woo. What's wrong with you? I'd rather you just talk like usual. Why is your breathing so heavy?"
