The afternoon Lin Xuan went to Lin Yue's school, the sky carried that clear, deceptive color calm days often have before they become complicated. He had promised to attend his sister's presentation about the historic bridges of Yunhe, one of those promises that might seem small in other families. In his, where hospital schedules constantly threatened to swallow everything else, it meant much more.
He arrived five minutes late and with the absurd feeling of stepping into a world that no longer belonged to him. Yunhe Secondary School still smelled of old chalk, damp corridors, and cafeteria food. The walls were covered with posters about exams, science competitions, and school cleanliness campaigns. A group of students played basketball in the yard while a teacher shouted at them not to run near the windows.
Lin Yue saw him from the second-floor corridor and raised a hand as if she wanted to pretend she did not care, though the speed of the gesture betrayed her.
"I thought you wouldn't make it," she said when he came closer.
"You and Mother have very little faith in me."
"We have experience. That's different."
Even so, her eyes were bright. Lin Xuan adjusted the collar of her uniform without thinking, and Lin Yue slapped his hand away in outrage.
"Don't do that in front of my classmates."
"Then don't make it so easy."
The presentations were being held in Classroom Five, a room with high windows, scratched desks, and a ceiling fan that sounded as if it were complaining about still being alive. Students' work had been mounted on colored boards. Lin Yue's display occupied a central panel and, to Lin Xuan's genuine surprise, looked quite good: carefully trimmed photographs, ordered dates, neatly drawn maps, and a red title properly aligned.
"So in the end you did understand aesthetics," he said.
She tried to look offended, but the corner of her mouth gave her away.
Parents began to arrive little by little. Mothers carrying bags of fruit, fathers still wearing factory uniforms, grandparents who walked slowly and looked around as if schools were changing too fast for their liking. Lin Xuan stayed somewhat to the side, conscious that here he was not "Doctor Lin," only the older brother of a smart and temperamental girl.
The history teacher, a small woman with a strong voice, called the activity to order. One by one, the students explained their projects. Lin Yue spoke well—clearly, without swallowing words, with the mixture of pride and boldness that sometimes drove Mei Lan mad and at other times made her laugh. As Lin Xuan listened to her describe the south canal bridge as a symbol of connection between old neighborhoods and newer districts, he felt an unexpected tenderness mixed with distance. He had spent so long trying not to drown inside the hospital that he had nearly failed to see how quickly his sister was growing up.
The moment broke ten minutes later.
First came a dull noise from the back of the room. A desk shoved abruptly. Then a nervous murmur. A thin, pale-faced student in the last row had tried to stand and collapsed sideways. Her classmates reacted late and badly, stepping away instead of catching her.
Lin Xuan was already moving.
"Give her space."
The teacher started to say something, but after recognizing him stepped aside. The girl was breathing, though fast. Her lips were dry, her forehead cold, her eyelids trembling. It did not look like trauma. It did not look like a seizure. More like a collapse from anxiety, fasting, and exhaustion mixed together.
"What's her name?" he asked while checking pulse and responsiveness.
"Wen Jia," Lin Yue answered, kneeling on the other side. "She didn't eat breakfast. Lately she hasn't been eating lunch properly either."
Wen Jia forced her eyes half open.
"Don't... don't call my parents."
That sentence alone explained more than any sign could. Lin Xuan helped position her on her side, asked for sweet water and fresh air, and spoke slowly, without severity.
"First we're going to make you feel better. Then we decide that."
The system flashed briefly.
[Observation: syncope or presyncope due to exhaustion, fasting, and stress.]
[Recommendation: basic stabilization, glucose check, follow-up.]
It was not a dramatic emergency, but it was real. And it was happening in a classroom full of teenagers who were suddenly looking at Lin Xuan as though someone from another kind of world had appeared among them.
The school nurse arrived carrying a too-modest first aid kit and an old glucometer. The glucose was low—not catastrophic, but enough to explain part of what had happened. Wen Jia improved after drinking slowly, breathing, and lying down with her legs elevated. While the teacher tried to regain control of the classroom, Lin Xuan spoke with her and the school nurse in the corridor.
"I don't think she needs an ambulance right now," he said, "but she should be seen in clinic if this happens again. And she shouldn't stay alone today."
The nurse nodded gratefully.
"We don't have many resources here," she admitted.
"I know that phrase."
The teacher, still tense, placed one hand against her chest.
"Good thing you came."
Lin Xuan looked through the classroom doorway. The students had lowered their voices. Some pretended not to stare; others stared openly.
"No. Good thing she collapsed here and not on her way home alone."
When he went back inside, Lin Yue was waiting beside her poster with her arms crossed.
"That was very dramatic."
"Are you jealous because for five minutes someone else was the center of attention?"
"I'm offended because she stole the audience during my best part."
He shook his head, amused.
The activity ended later than planned. Wen Jia left accompanied by the school nurse and an aunt who arrived in obvious haste. Before going, the girl looked at Lin Xuan and then at Lin Yue with a mixture of embarrassment and gratitude.
"Thank you," she murmured.
Lin Yue lifted one hand casually, as if trying to reduce the weight of the scene, but Lin Xuan could tell it had affected her more than she intended to show.
After they left the school grounds, they walked together toward the main avenue. Students spilled into the street like a disorderly river of backpacks, bicycles, and laughter. Lin Yue carried the rolled poster under her arm.
"Wen Jia is pushing herself too hard," she said suddenly. "She wants to get into a better preparatory school than this one, and her family never stops talking about it."
"That doesn't help anyone remember to eat."
"No. But everyone here does some version of the same thing. Some people just break sooner."
The sentence sounded strangely adult.
They stopped at a skewer stand near the bus stop. Lin Xuan bought two and a hot soy milk. Lin Yue bit into hers with restrained hunger.
"Did it happen to you too?" she asked without looking at him.
"What thing?"
"That feeling that if you weren't better than everyone else, you'd be left behind."
Lin Xuan took longer than usual to answer.
"Yes."
"Does it go away?"
He watched the steam rise from the soy milk.
"Not entirely. You just learn to decide what price you're willing to pay."
Lin Yue glanced sideways at him.
"That sounds depressing."
"It's honest."
She snorted and kept eating. After a moment she nudged his arm.
"Don't become one of those people who says honest things but is unbearable to listen to."
"I'll do my best."
They walked to Canal Station instead of taking the bus. The sunset painted the buildings orange and the river reflected long strips of light. Lin Xuan thought about the classroom, about Wen Jia, about the way fear of failure could make someone sick before they were old enough to name it. In the hospital he saw bodies collapsing; outside it, he was beginning to notice the cracks that came first.
When they got home, Mei Lan listened to the full story while making tomato-and-egg soup. She reacted with alarm to the student fainting, but by the third sentence she was already asking whether Lin Yue had eaten properly at school.
"Yes, Mom."
"I'm asking because apparently people in your class are dropping unconscious now."
Lin Yue opened her mouth to protest, but Lin Xuan answered first.
"She hadn't been eating properly. And she was exhausted."
Mei Lan set the spoon down on the pot.
"Then listen," she said, looking first at her daughter and then at him. "Neither grades nor work are worth a broken body. I want both of you to remember that."
The sentence remained floating in the kitchen—simple and final. Lin Xuan thought of the bridge, of Mr. Peng, of Dr. Sun's notebook. There were too many ways to arrive late to a person.
That night, after everyone went to bed, he opened the system and reviewed the pending notifications.
[Community event: non-hospital stabilization.]
[Reward: +Medical EXP.]
[Supplemental learning: not every collapse begins on a stretcher.]
[Merit Funds: preventive-care training bonus.]
Lin Xuan closed the screen and rested his head against the wall.
In Classroom Five there had been no scalpels, no monitors, no department heads. Yet he had understood something important: medicine did not consist only of intervening when a body fell. It also meant learning to recognize the kind of pressure that pushed someone toward that edge.
If he wanted to reach the top, he would have to master surgery.
But if he wanted to truly deserve that summit, he would also have to understand people before they became patients.
