The first practical example was harmless.
That made it worse.
Khoa demonstrated how to place an open hand between two arguing students without pushing. Another Trưng Vương boy demonstrated how to guide someone away from a crowd. The facilitator praised their control. Teachers nodded. Phones recorded the correct parts.
Lâm watched feet.
Feet lied less than smiles.
Khoa's feet always gave him the better angle before his hands did anything useful. A half-step outside. Weight never too far forward. No wasted bounce. Not a street brawler showing courage. Someone trained to let other people look like the problem.
He did not move like the street attackers Lâm had heard about in fragments. He did not move like the basketball attackers either, all shoulder and rushed breath. Khoa's body stayed polite. Even his balance looked like it had been written for a report.
That was harder to hate.
Lâm hated it anyway.
Then Khoa turned to Lâm.
"Your turn. Just stand here."
"For what?"
"Recovery scenario. We show how to assist an injured student."
Assist.
Support.
Guide.
Clean words kept arriving with dirty hands.
Lâm stepped onto the mat because refusing inside the microphone circle would make refusal the story, not because Khoa told him.
He stood with his wrapped hand close to his chest and his feet slightly wider than the rehab specialist would have allowed if she were watching. The mat was softer than the clinic floor. Softer meant slower. Slower meant falling would steal more time.
Khoa smiled.
"Relax."
"No."
The facilitator laughed, thinking it was nerves.
Khoa did not laugh.
His hand came toward Lâm's shoulder. Open palm. Correct angle. Perfect for photos.
Lâm did not move away.
Not yet.
Khoa's thumb pressed one inch too low, near the nerve line that made the arm want to fold. It would not bruise. It would not show. It would teach the injured side to panic.
Lâm let the pressure land.
Then he turned his torso, not his wrist.
Small.
Ugly.
Enough to make Khoa's hand slide from shoulder to sleeve.
Pain ran down the arm like a match struck inside the bone. Lâm wanted to jerk away. That was what Khoa wanted too. A jerk would become resistance. Resistance would become difficult student. Difficult student would become unsafe.
So Lâm breathed through his teeth and let the movement look clumsy.
Clumsy was useful.
Clumsy gave adults a version they could accept without understanding the fight.
Someone clapped politely.
The facilitator said, "Good, very natural."
Khoa's eyes changed with correction rather than anger.
He stepped closer for the second demonstration.
"Sometimes students resist help," he said.
There it was.
The room heard teaching.
Lâm heard accusation.
Khoa's second hand went toward the wrapped wrist.
Lâm stepped back before contact.
"Please explain the grip before touching the injury," he said loudly enough for the nearest teacher to hear.
The facilitator's smile faltered.
Mai An's camera clicked once at the facilitator's face rather than Khoa.
Khoa lowered his hand.
"Of course."
He had lost the mat.
So he changed rooms.
During the break, two Trưng Vương boys moved a stack of chairs toward the side corridor. Another asked Lâm to help with water bottles near the basement stairs. A fourth stood too casually near Mai An's media table.
The group suggested a route rather than surrounding Lâm. That was smarter.
One boy lifted a crate of bottled water and nodded toward Lâm like they had already spoken.
"Can you help?"
The sentence was perfect. Public. Small. Kind. It made refusal look selfish and agreement look scheduled.
Lâm pointed at his wrapped hand.
"Ask someone with two hands."
The boy's smile stayed on too long after the answer.
Lâm walked toward the toilet hall instead.
His phone vibrated.
Tân Phong:
Do not use toilet hall. Khoa's second boy entered without bag.
Another buzz.
Quân:
Outdoor court soon. They want school pride, not hidden hall.
Then Thuận:
Stay public. If public turns against you, go toward noise, not away.
Lâm looked at the hall.
Main room too watched.
Side corridor too clean.
Basement too quiet.
Outdoor court too loud.
Every route had teeth.
He chose the loud one.
Outside, the court still held rainwater in thin patches near the painted lines. A banner frame leaned against the wall. Plastic stools sat under an awning. Students were gathering there because break time liked open air.
The court was not a basketball court, not really. It was a school-event rectangle with old painted lines that had survived too many uses: morning exercise, youth meetings, temporary parking, photo lines, speeches nobody remembered. The hoops were gone. Only the height marks on the wall remained, dirty rectangles where something used to be bolted.
That bothered Lâm more than it should have.
An empty court still knew how to make a body remember a game.
Khoa arrived thirty seconds later.
Bảo Khang followed at a distance.
This time, there was no microphone.
Only phones.
Group Three was assigned to movement demonstration.
Of course it was.
Nothing made contact look innocent faster than a facilitator with a microphone saying the word demonstration.
Khoa stood at the edge of the mat and explained spacing to students who did not know they were already being placed. He put one Trưng Vương boy near the banner frame, another by the awning pole, and Lâm between a wet line and the stacked stools.
"We show how to de-escalate," Khoa said.
His hands stayed open.
Open hands photographed well.
Lâm looked at the mat, then at the outdoor court beyond the awning. More rain. More witnesses. Less control.
"Can we do it outside?" he asked.
The facilitator blinked. "Outside?"
"More space. Easier for people to see."
Khoa's smile held.
Only held.
That was the first useful crack.
Mai An lifted her camera toward the outdoor court before anyone approved it. A small movement. Not support. Preparation.
The facilitator, afraid of looking afraid, agreed.
As the group moved, Khoa passed close enough for Lâm to hear him.
"You like public rooms."
"I like exits."
"Same thing until the phones come out."
Lâm did not answer.
The old version of him would have tried to win the sentence.
The new version counted stools.
