Xinyue read the message twice. Then the third time, slower like the words might rearrange themselves into something less ominous if she stared long enough.
Stay where you are.
Yuerin leaned closer. "That him?"
Xinyue nodded.
"Good," Yuerin said. "Because I was about to suggest we sprint."
"That won't help."
"Neither will standing still."
"Standing still," Xinyue said, "is exactly what he told me to do."
Yuerin let out a quiet, humorless laugh. "That's comforting. In a 'this is how people die' way."
The corridor buzzed with movement. Stretchers rolling past, voices calling names, the soft chime of elevators opening and closing. The hospital swallowed fear easily. It wrapped danger in white walls and fluorescent light and made it feel manageable.
But Xinyue knew better. Hospitals didn't make danger disappear; they just made it quieter.
Her phone vibrated again. This time, she didn't wait.
'Where are you?'
She typed back with her thumb, quick and precise. 'At work.'
The reply came almost instantly. 'Don't leave the building.'
Yuerin snorted under her breath. "You, see? I told you running was a bad plan."
Xinyue slipped the phone into her pocket. "I'm not running."
"You're following instructions."
"That's different."
"Barely."
They stood there for a moment longer, both of them listening to footsteps, to voices, to the absence of anything obviously wrong.
Then Xinyue straightened her shoulders. "I need to change," she said. "Rounds start in ten."
Yuerin stared at her like she was witnessing a personal betrayal. "You're prioritizing rounds?"
"I'm prioritizing normal," Xinyue replied. "Because if I don't, this…" she gestured vaguely at the air between them, "…wins."
Yuerin pressed her lips together, clearly unconvinced, but followed as Xinyue turned toward the locker rooms. They walked side by side, their pace unhurried. Anyone watching would see two women heading to work, nothing more.
Then Xinyue felt it again. That quiet pressure, not the eyes this time but movements. The sense that something had shifted just out of her field of vision.
She stopped short.
Yuerin almost collided with her. "What the…"
"Listen."
They stood still. A gurney rolled past. Someone laughed behind them. A door opened, then closed. Nothing out of place.
But Xinyue's pulse had begun to quicken anyway.
"Tell me you don't feel that," she murmured.
Yuerin hesitated. "I feel… watched."
"Not watched," Xinyue said. "Tracked."
The word felt right the moment she said it.
Yuerin's jaw tightened. "What a surprise…?"
"Yes??" They resumed walking again.
This time, Xinyue paid attention to reflections, the shine on the tiled floor, the glass panels along the corridor, the faint distortions in stainless steel surfaces. A man stood near the vending machines, his attention on the screen as he pressed a button. Another leaned against the wall near the stairwell, scrolling on his phone.
Ordinary.
All of it feels like ordinary and that was the problem. The locker room door closed behind them with a soft thud.mThe space was empty, quiet except for the hum of ventilation. Xinyue set her bag down and opened her locker. Her hands were steady.
That surprised her too.
"You're calm," Yuerin said.
"I'm functioning."
"Not the same thing."
Xinyue changed quickly, slipping into scrubs, tying her hair back. She caught her reflection in the mirror eyes a little darker, jaw set more firmly than usual.
She looked… alert. Not afraid.
That unsettled her.
Yuerin hovered near the door, arms crossed. "I don't like this."
"I know."
"Say it with more concern."
"I am concerned."
"That was not convincing. I can adjust with that.."
Xinyue met her gaze in the mirror. "If something happens, you leave."
"Don't start."
"I'm serious."
"You're not doing the dramatic self-sacrifice thing."
"It's not dramatic. It's practical."
Yuerin scoffed. "You're a doctor, not an action heroine."
"Yet."
Yuerin shook her head, exasperated. "You've changed."
Xinyue paused, fingers resting on the edge of the locker. "No," she said quietly. "I've been reminded."
"Of what?"
"That not everything dangerous looks dangerous."
They left the locker room together. The corridor seemed louder now. Too loud for their liking. Xinyue took three steps before her phone vibrated again. She stopped.
Yuerin sighed. "Please tell me it's not another cryptic message."
Xinyue checked.
"They're inside."
Her stomach dropped.
"Inside what?" Yuerin asked.
"The building," Xinyue said.
Yuerin went very still. "Okay," she said slowly. "We're leaving."
"No."
Yuerin grabbed her arm. "Xinyue… it's not the time."
"They won't attack here."
"You don't know that."
"I do."
"How?"
"Because if they were going to," Xinyue said, voice low, "they wouldn't be warning me."
Yuerin searched her face. "You sound very sure."
"I'm not."
"Then why???"
"Because danger doesn't knock twice," Xinyue said. "And this feels like the first."
They stood there, tension stretched tight between them. Then a voice cut through it.
"Dr. Lin."
Xinyue turned. Dr. Ong stood a few steps away, a chart in his hand, concern etched clearly across his face.
"There you are," he said. "We've been looking for you."
"Looking?" Xinyue echoed.
"Yes. Security flagged an issue near the east wing. We're restricting movement for a bit."
Yuerin stiffened. "What kind of issue?"
Dr. Ong hesitated. "Unidentified individuals."
Xinyue felt the pieces slide into place.
"How many?" she asked.
"Two that we know of."
That matched. Yuerin's grip tightened on Xinyue's arm.
Dr. Ong lowered his voice. "They asked about you."
The words landed heavily. Xinyue didn't ask how he knew. She didn't ask what they looked like.
She already knew enough.
"What did you tell them?" she asked.
"That you were on shift," he said. "And that patient confidentiality applies."
Her throat tightened. "Thank you."
He studied her carefully. "Do you know them?"
"No," Xinyue said.
Not a lie. Just an incomplete truth.
He nodded slowly. "Security will handle it. Stay in populated areas."
Yuerin snorted softly once he turned away. "That's reassuring. Very 'we've got this' energy."
Xinyue checked her phone again. No new messages.
She took a breath. "I need to go to the east wing."
Yuerin stared at her. "You absolutely do not."
"That's where they are."
"That's where danger is."
"Yes."
"And you want to go toward it?"
"I want to see them before they see me."
Yuerin opened her mouth, then closed it.
"…You're serious."
"I am."
"This is a terrible idea."
"Probably."
"And you're still doing it."
"Yes."
Yuerin sighed, defeated. "Fine. But I'm coming."
This time Xinyue looked at her. Really looked, "You need to be somewhere safe," she said gently.
"And you don't?"
"I need to be visible."
Yuerin swallowed. "You sound like him."
Xinyue didn't deny it. They parted at the junction of the corridor, Yuerin reluctantly heading toward a nurses' station, casting worried glances back until Xinyue was out of sight.
The east wing felt different.
Quieter.
Less traffic.
The lights hummed softly overhead. Xinyue walked steadily, her steps measured. She counted doors. Monitored reflections. Adjusted her pace. Halfway down the hall, she felt it again.
That shift.
This time, she didn't stop.
Didn't turn.
She just said, softly "I know you're there."
Footsteps slowed behind her. Then stopped. "Good," a man's voice said. "I was hoping you would."
Xinyue turned around. The man stood a few meters away, posture relaxed, hands visible. He wasn't the one from earlier. This one was older, his gaze sharper, more calculating.
"You shouldn't be here," she said.
He smiled faintly. "Neither should you."
"What do you want?"
"To understand why he's interested in you."
Her pulse quickened. "I'm not interesting."
"You are now."
She held his gaze. "That's not my problem."
He tilted his head. "You treated him."
"I treat people."
"You saved him."
She said nothing.
The silence stretched.
"He's coming," the man said.
Xinyue's breath caught despite herself.
"When?"
"Soon."
"Why tell me?"
"Because I wanted to see you first."
"And?"
"And you're not what I expected."
"That's disappointing."
"For you," he agreed. "Not for him."
Before she could respond, a sound echoed down the corridor.
Footsteps.
Faster.
He glanced past her, then back.
"Lucky timing," he said.
Then he stepped back and vanished into a side corridor like he'd never been there at all.
Xinyue stood frozen for a beat. Then her phone buzzed.
"Don't move."
She exhaled slowly.
Because this time, she could hear him coming. The danger, she realized, didn't knock twice.
It simply arrived.
