Ye Fan got back just past midnight.
Mu Chen knew it before he even saw him. The whole floor felt different when Ye Fan returned from wherever he'd been – heavier, quieter, even the lights seemed sharper, though they hadn't changed.
Mu Chen was sitting on his bed behind the partition, still in his uniform pants and dark shirt, trying to look like he was reading his notebook.
Then he heard footsteps in the hall. One set. Heavy. Measured. Too controlled.
It was Ye Fan.
Nobody greeted him. That told Mu Chen everything he needed to know: the stability review hadn't gone well.
A minute later, Lin Lan hurried past the partition, clutching her tablet. Zhou Xiao followed, his jaw tight, eyes fixed straight ahead.
Mu Chen put his notebook down and waited.
Then Ye Fan's voice came from outside the partition. "Mu Chen."
Mu Chen stood up immediately. "Yes?"
Ye Fan didn't step inside. He stayed at the edge of the partition, one hand on the frame, his face impossible to read. "Come out."
Mu Chen followed him into the ready room. Only half the lights were on. The table screen was black. The kettle in the corner had gone cold. Lin Lan stood by the lockers. Zhou Xiao was leaning against the wall. Colonel Luo Wei stood near the window, arms crossed.
Something official had gone down.
Luo Wei looked at Mu Chen and spoke first. "The institute amended Major Ye Fan's file," she said.
Mu Chen's chest tightened. "How?"
Luo Wei's voice remained steady. "Additional observation. Restricted independent mission command for two weeks. Mandatory follow-up."
Zhou Xiao let out a quiet curse. Lin Lan looked exhausted. "They wanted more."
Of course they did. Mu Chen's eyes flicked to Ye Fan. His face was eerily calm, the kind of calm that meant anger had sunk too deep to show.
Luo Wei continued, "They also added a note." Mu Chen stayed silent. Luo Wei's gaze sharpened. "A recommendation that guide support around Major Ye Fan be formally reviewed."
Mu Chen froze. Not assigned. Not paired. Reviewed. A formal note. A system linking two names and calling it procedure.
Zhou Xiao pushed off the wall. "That's not a recommendation. That's a trap."
Lin Lan nodded. "Yes."
Luo Wei looked at Ye Fan. "What did you say in the room?"
Ye Fan's jaw tightened. "Nothing useful."
Lin Lan made a small sound, half disbelief. "Then they already had enough." Mu Chen understood. The gate footage. The mission data. The way Ye Fan's readings spiked around him. The institute didn't need words; they had patterns.
Luo Wei looked at Mu Chen. "From now on, there is a written note connecting your field effect to Major Ye Fan's stability shifts."
Mu Chen asked quietly, "How formal?"
Luo Wei's answer was immediate. "Formal enough." That was bad. Not a rumor. Not a suspicion. Not hallway gossip. Formal enough meant file language. Clear enough to cause problems.
Ye Fan finally spoke. His voice was low, rough, tightly controlled. "They asked if I wanted assignment review."
No one in the room moved. Mu Chen's fingers curled slightly at his sides. Luo Wei's eyes narrowed. "And?"
Ye Fan's gaze remained fixed ahead. "I said no."
Zhou Xiao let out a relieved breath. Lin Lan closed her eyes for a second. Mu Chen stood perfectly still. He knew Ye Fan would say no. Still, hearing it sent a small, painful pang through his chest. Not because he wanted the assignment. Because he understood what Ye Fan had refused. Safety on paper. Control disguised as care. A legal chain around both of them.
Luo Wei spoke again. "The refusal is also in writing." A line in ink. One note to link them. One note to refuse the link. The system liked records because records could be used later.
Lin Lan checked her tablet. "The review note hasn't been fully circulated yet. We have a little time." Zhou Xiao looked at Ye Fan. "Can we fight it?"
Luo Wei answered before Ye Fan could. "Not directly." Ye Fan's mouth tightened. "Then indirectly." Luo Wei held his gaze. "Meaning?"
Ye Fan looked at Mu Chen then. Directly at him. His eyes were dark and sharp and weary in a way Mu Chen hadn't seen before. "Meaning," Ye Fan said, "he does nothing they can use."
Mu Chen understood. No visible help. No calm pulses. No stepping in. No hands on sleeves. No proof.
Luo Wei nodded. "Agreed." Lin Lan added, "And no one says the word compatibility unless forced." Zhou Xiao let out a humorless laugh. "A little late for that." Nobody answered. The room fell silent. Mu Chen could feel the weight of the file now, even without seeing it. A line in ink. A note that said he affected Ye Fan. A refusal that said Ye Fan knew it too.
Luo Wei dismissed them after that. "Sleep if you can," she said. Nobody looked like they could. Lin Lan left first. Then Zhou Xiao. Ye Fan stayed. Mu Chen stayed too. The room felt bigger with just the two of them, and somehow more dangerous.
Ye Fan walked to the dark table screen and rested both hands on the edge. His head was slightly lowered. Mu Chen watched him for a moment, then asked quietly, "Did they push hard?"
Ye Fan gave a short breath. "Hard enough."
Mu Chen stepped closer, but not too close. "Did you break anything?"
Ye Fan's mouth twitched faintly. "Not this time." Mu Chen almost smiled. Almost.
Ye Fan looked at him over his shoulder. "They asked about you ten different ways." Mu Chen's chest tightened. "And you said no."
"Yes."
Silence stretched. Then Ye Fan turned fully toward him. His voice dropped lower. "Do you know what else they asked?"
Mu Chen shook his head once. Ye Fan's eyes stayed on his face. "They asked if your touch felt instinctive."
Mu Chen froze. Ye Fan kept looking at him. "I said I didn't know," Ye Fan said. The room felt too quiet. Mu Chen's voice came out soft. "Do you?"
Ye Fan didn't answer right away. When he did, his voice was rough and honest, like it was being dragged out of him. "Yes."
Mu Chen's throat tightened. Because he knew exactly what Ye Fan meant. Not romance. Not yet. Not safety. Not even trust. Instinct. A body learning another body before the mind agreed. The way Ye Fan turned when Mu Chen breathed too sharply. The way Mu Chen reached when Ye Fan's control slipped. The way both of them stopped just before touching and felt it anyway.
Ye Fan looked away first. "They put it in the file," he said. "Not those words. But close enough."
Mu Chen stood in the half-lit ready room and understood one simple, terrible thing. The system had noticed the pull between them before either of them had named it. That was how systems worked. They found the line. Then they wrote over it in ink.
Mu Chen looked at Ye Fan and said quietly, "Then we stop giving them anything."
Ye Fan's eyes lifted back to his. For one second, Mu Chen thought Ye Fan might argue. Instead, Ye Fan nodded once. "Fine," he said. Then, after a pause, he added in the same low voice, "But if they try to move you, I won't follow that rule."
Mu Chen's chest tightened again. He kept his face calm. "Ye Fan—"
Ye Fan cut him off. "Sleep." It wasn't really an order. It was the only safe thing left to say.
Mu Chen went back behind the partition and sat on the bed. He looked up at the camera. Cold light. Clean ceiling. A silent witness. Somewhere in the base, there was now a record with both their names near each other. And no matter how careful they were next, Mu Chen knew this much: Ink spread.
