The simulation order came in right at dawn. Lin Lan spotted it first. Mu Chen knew because the ready room suddenly got this new kind of quiet, the kind that happens when something on a screen confirms what everyone's been too afraid to say out loud.
Mu Chen stepped out from behind his cubicle and saw Lin Lan standing by the table, tablet in hand, her face a mix of calm and tension. Zhou Xiao was right there with her, already looking annoyed. Ye Fan was across the room in his full training gear, standing so rigidly he looked like he could cut glass.
"What is it?" Mu Chen asked.
Lin Lan read the order straight from the screen. "Joint field simulation. Guide-sentinel response observation. Major Ye Fan and Lieutenant Mu Chen assigned for a compatibility stress test."
Silence fell. Mu Chen's chest clenched for a second, then relaxed. There it was. Not a suggestion. Not a heads-up. Not a whisper. An actual order.
Zhou Xiao muttered, "They're not even trying to hide it anymore."
Lin Lan kept reading. "Contact is allowed under approved test conditions. Mental output recording is mandatory. Institute observers will be present."
Ye Fan's expression didn't change at all. That was scarier than anger. "When?" he asked.
Lin Lan looked at the bottom of the order. "Today. Fourteen hundred."
Too soon. Of course it was too soon. The institute loved speed when it meant people had less time to push back.
Colonel Luo Wei walked in then, as if the order had summoned her. "I saw it," she said.
Ye Fan turned to her. "Refuse it."
Luo Wei's gaze was steady. "I already did."
Mu Chen froze. Ye Fan's eyes narrowed. "And?"
Luo Wei's mouth tightened. "Denied."
Permit denied. The system loved that phrase. It made restrictions sound like just another piece of paperwork. Zhou Xiao swore out loud this time. Lin Lan looked down at the tablet like she wanted to smash it.
Mu Chen asked the only question that mattered. "Can they force a link?"
Luo Wei answered immediately. "No formal link without signed approval." A small wave of relief washed over Mu Chen.
Luo Wei continued, "But they can push contact, stress, and response conditions right up to the edge." And there it was again. A moment of freedom, followed by a trap.
Ye Fan stepped closer to the table. "Then I won't give them a response."
Luo Wei's voice sharpened. "That's exactly what they want to test. If you go blank, they mark you as resistant. If you react, they mark you as compatible. If you refuse, they mark you as unstable."
Ye Fan stared at her. Mu Chen watched him intently. The institute had designed a system where every choice led to a black mark.
Luo Wei looked at Mu Chen next. "You keep it at C-class."
Mu Chen nodded. "Yes, ma'am."
Ye Fan's voice cut in. "No."
Everyone looked at him. Ye Fan didn't even blink. "If he stays too low, they'll push harder." Mu Chen's stomach twisted. That was true. Ye Fan looked at Luo Wei. "They'll keep increasing the pressure until they get the result they want. It's better to give them something they can control."
Lin Lan's eyes narrowed. "Upper C-class range." Mu Chen turned his head to look at her. Lin Lan nodded once. "Enough to maintain the cover. Not enough to break it."
Zhou Xiao said, "You're all talking like this is normal."
Nobody answered him. Because it wasn't normal. It was survival.
Luo Wei made the decision. "Fine. Controlled upper range only. No improvising." Her eyes landed on Ye Fan. "And no heroics."
Ye Fan's mouth tightened. "Yes, ma'am."
The briefing ended, but no one moved immediately. The room remained filled with that same tense silence. Mu Chen turned back toward his cubicle, thinking he had a few hours to get himself together.
Ye Fan's voice stopped him. "Mu Chen."
Mu Chen turned back. Ye Fan glanced at the others once. "Walk with me." Lin Lan's eyes flickered between them, then down to her tablet. Zhou Xiao pretended to be intensely interested in his coffee.
Mu Chen followed Ye Fan into the side corridor. The lights hummed overhead. Cold. White. Steady. Ye Fan stopped near the storage room and turned to face him.
"If they push for touch," Ye Fan said, "you don't panic."
Mu Chen blinked. "You think I panic?"
Ye Fan's eyes dropped for a second to Mu Chen's mouth, then back up. "No. That's part of the problem." Mu Chen's chest tightened.
Ye Fan stepped closer. Not too close yet. Close enough to feel. "They're going to watch your face," Ye Fan said. "Your hands. Breathing. Pupils. Everything."
Mu Chen nodded. "I know."
Ye Fan's jaw clenched. "Then stop looking at me like that."
Mu Chen went still. "Like what?"
Ye Fan let out a short, rough breath of frustration. "Like I'm the only thing in the room." The words hit hard. Because Mu Chen hadn't realized it showed. Because Ye Fan had clearly noticed. Because it meant Ye Fan was watching just as closely.
Mu Chen's voice came out soft. "And you?"
Ye Fan stared at him. For a dangerous second, he said nothing. Then: "Worse."
Mu Chen's breath hitched. The corridor suddenly felt too small. Ye Fan took another step, and now they were close enough that Mu Chen could feel warmth radiating through the air between them.
"When they ask for contact," Ye Fan said, his voice low and rough, "I'll keep it brief." Mu Chen nodded, though his heart was no longer entirely steady.
Ye Fan's eyes dropped again. Mouth. Throat. Hands. Back to eyes. It wasn't subtle. Not anymore.
Mu Chen whispered, "Ye Fan…"
Ye Fan cut him off. "If I touch you there, don't react."
Mu Chen swallowed. Easy instruction. Impossible instruction. Ye Fan seemed to realize that too, because a dark, humorless almost-smile touched his lips and vanished. "That wasn't fair," he said.
Mu Chen looked at him. "No."
A beat of silence. Then Ye Fan lifted his hand. Slowly. Mu Chen froze, every nerve suddenly on high alert. Ye Fan's fingers stopped just short of Mu Chen's jaw, hovering the same way they had that night. The same almost-touch. The same heat. The same unbearable restraint.
Then Ye Fan slid two fingers lightly under Mu Chen's chin and raised it by a fraction. Actual contact. Small. Controlled. Devastating. Mu Chen's whole body went rigid.
Ye Fan's eyes darkened instantly, because he felt the response even if Mu Chen didn't show it on his face. "This," Ye Fan said softly, his thumb barely brushing the line beneath Mu Chen's lower lip before he pulled back, "is too much."
Mu Chen's chest felt so tight it hurt. He managed, barely, "For the test?"
Ye Fan's voice dropped lower. "For me."
Silence. Clean hallway. Cold light. One sentence that changed everything. Then footsteps echoed from the main corridor. Ye Fan stepped back instantly, all warmth gone, replaced by the sharp lines of command.
Lin Lan appeared at the corner. "Simulation prep in twenty," she said. Her expression gave nothing away, but her eyes were too knowing.
Ye Fan nodded once. "We're coming."
Lin Lan left. Mu Chen looked at Ye Fan. Ye Fan looked at him for one last second and said, rough and quiet, "Keep your face empty in there." Mu Chen nodded.
But as they walked back toward the ready room, one thing stayed under his skin like a burn. Permit denied. Refusal denied. Distance denied. And somewhere between all those denials, Ye Fan had admitted the truth: The problem was no longer just the institute. It was what Ye Fan wanted when he touched him.
