Wei Wuxian opened his eyes and immediately knew something was wrong.

The ceiling above him was made of carved wood, not concrete. The air smelled like incense, not smoke and machines. His clothes were long, white, and tied with a ribbon.

“This is not my apartment,” he muttered.

A sharp pain hit his head, and unfamiliar memories flooded his mind.

Omega.

Ancient era.

Gusu Dukedom.

Wei Wuxian sat up. “You’re telling me I died in the future and woke up as an omega?”

A calm voice echoed in his mind.

Timeline stabilized.

Wei Wuxian sighed. “Of course.”

Before he could think more, the door opened.

A servant bowed deeply. “Young Master Wei, the imperial decree has arrived.”

“Ah,” Wei Wuxian said lazily. “That sounds dangerous.”

Arranged to the Cold Duke

The imperial hall was silent.

Wei Wuxian stood among strangers, trying not to laugh at how serious everyone looked.

The minister cleared his throat.

“By order of His Majesty, Wei Wuxian shall marry Duke Lan Wangji of Gusu.”

Wei Wuxian blinked. “That was fast.”

Heavy footsteps echoed.

Lan Wangji entered the hall.

Tall. Calm. Cold eyes. Alpha aura strong enough to make other alphas step back.

Wei Wuxian looked him up and down.

Wow. Handsome. Deadly. Definitely dangerous.

Lan Wangji looked at Wei Wuxian.

And stopped.

For the first time in years, his heart skipped.

“This is my omega,” Lan Wangji said quietly.

Wei Wuxian raised an eyebrow. “Sir, you don’t even know me.”

Lan Wangji nodded. “I will learn.”

The minister asked nervously, “Duke Lan… do you accept?”

“I accept.”

No hesitation.

Wei Wuxian smiled. “Guess I’m married now.”

Living with the Duke

The Duke’s residence was too quiet.

Wei Wuxian noticed it the moment he stepped inside. No shouting servants, no loud conversations, no unnecessary movement. Everything was neat, clean, and calm.

“This place feels like a library that learned how to walk,” Wei Wuxian said.

The servants froze.

Lan Wangji paused, then said calmly, “If you dislike it, I can change it.”

Wei Wuxian blinked. “No, no. I was joking. It’s… peaceful.”

Lan Wangji nodded, as if this answer mattered a lot.

Wei Wuxian was given a large room connected directly to the Duke’s chambers.

He stared at the door between them.

“…That’s fast,” he muttered.

A servant whispered, “Young Master, you are the Duke’s omega now.”

Wei Wuxian waved his hand. “Relax. I don’t bite. Usually.”

That evening, they had dinner together.

Lan Wangji sat straight, elegant, silent.

Wei Wuxian ate like he hadn’t seen food in days.

Lan Wangji quietly placed more dishes near him.

Wei Wuxian noticed. “You’re feeding me like I’m a rare animal.”

“You are important,” Lan Wangji replied.

Wei Wuxian paused for half a second, then smiled.

“You say scary things very calmly, Duke.”

Lan Wangji looked at him seriously. “Do you want me to stop?”

Wei Wuxian laughed. “No. It’s kind of nice.”

After dinner, Lan Wangji spoke again.

“There are rules,” he said.

Wei Wuxian leaned forward. “I knew it.”

Lan Wangji continued, “You may go anywhere in the dukedom.

You may study, train, or rest.

No one may command you except me.”

Wei Wuxian raised a finger. “And you?”

Lan Wangji met his eyes. “I will ask, not command.”

Wei Wuxian stared at him, surprised.

“…You really are a green flag.”

“I still do not know this flag,” Lan Wangji said.

Wei Wuxian laughed so hard he almost fell off the chair.

That night, Wei Wuxian lay on the bed, staring at the ceiling.

Cold duke. Powerful alpha. Respectful. Handsome.

This marriage might not be terrible.

In the next room, Lan Wangji stood silently.

He listened to Wei Wuxian’s breathing through the wall.

My omega is safe, he thought.

That is enough.

By the third day in the Duke’s residence, Wei Wuxian was bored.

Very bored.

The servants walked carefully, spoke quietly, and treated him like glass.

“I’m not going to break,” Wei Wuxian told a maid.

“Unless someone pushes me down the stairs.”

The maid turned pale. “Please don’t test that, Young Master.”

Wei Wuxian sighed. “This house needs entertainment.”

So he went exploring.

He wandered into the training grounds.

Dozens of soldiers froze when they saw him.

An omega.

The Duke’s omega.

Wei Wuxian smiled brightly. “Hello.”

No one answered.

Wei Wuxian picked up a wooden sword from the rack.

“Do you mind?”

Before anyone could stop him, he swung.

The movement was smooth. Fast. Perfect.

The sword stopped a hair’s breadth from a training dummy’s neck.

The soldiers stared.

Wei Wuxian blinked. “Ah… muscle memory.”

He laughed awkwardly and dropped the sword. “I used to exercise.”

Unfortunately, Lan Wangji arrived just in time to see everything.

The soldiers immediately knelt. “Duke!”

Wei Wuxian turned around slowly.

“Oh,” he said. “You weren’t supposed to see that.”

Lan Wangji’s eyes were sharp, focused—not angry.

“You can fight,” he said.

Wei Wuxian scratched his cheek. “A little.”

Lan Wangji nodded once. “Good.”

That was it.

No questioning. No suspicion.

Wei Wuxian stared. “That’s… all?”

“You are my omega,” Lan Wangji replied. “I trust you.”

Wei Wuxian felt something warm in his chest.

Dangerous, he thought. This man is dangerously nice.

Later that day, rumors spread.

“The Duke’s omega is strange.”

“He laughs too much.”

“He went to the training ground!”

Wei Wuxian overheard everything while eating snacks.

.

“So famous already,” he muttered.

That evening, Lan Wangji brought him tea.

“For your heat cycles,” he said calmly.

Wei Wuxian nearly choked. “You say that like you’re offering sugar.”

Lan Wangji looked serious. “Is that… incorrect?”

Wei Wuxian laughed until his stomach hurt.

That night, Wei Wuxian leaned against the window, looking at the moon.

This world is dangerous, he thought.

But this duke… he might be worth staying for.

Lan Wangji stood beside him, close but not touching.

“Sleep,” he said softly.

Wei Wuxian smiled. “Yes, husband.”

Lan Wangji’s ears turned red.

That's all

Lan Wangji had fought on countless battlefields.

He had faced enemies, bloodshed, and death without hesitation.

Yet nothing had prepared him for this.

His omega was laughing.

Wei Wuxian sat in the garden, surrounded by servants, explaining something in a lively voice. He used his hands dramatically, his expressions changing every second.

“And then I thought—why not try it backwards?” Wei Wuxian said, grinning.

The servants laughed. They were relaxed.

Comfortable.

Lan Wangji stood at a distance, watching.

This is dangerous, he thought.

I like this too much.

Later that afternoon, a young noble visited the dukedom.

He bowed deeply. “I greet the Duke… and the Duke’s omega.”

Wei Wuxian waved cheerfully. “Hi.”

The noble smiled a bit too brightly. “I have heard much about you, Young Master Wei.”

Lan Wangji’s gaze sharpened.

Wei Wuxian tilted his head. “All good things, I hope.”

The noble laughed. “Naturally. You are quite famous.”

Lan Wangji stepped forward.

“My omega does not receive guests alone,” he said calmly.

The noble stiffened. “O-Of course.”

Wei Wuxian looked at Lan Wangji. “You jealous?”

“I am observant,” Lan Wangji replied.

Wei Wuxian laughed. “Sure you are.”

That evening, they walked together through the lantern-lit corridors.

Lan Wangji spoke quietly. “If you are uncomfortable with visitors, I will refuse them.”

Wei Wuxian blinked. “You really don’t have to guard me like a treasure chest.”

Lan Wangji stopped.

“You are more valuable than that.”

Wei Wuxian stared.

“…You’re very bad for my heart, Duke.”

Lan Wangji nodded. “I accept responsibility.”

That night, Wei Wuxian couldn’t sleep.

He turned to see Lan Wangji sitting at the table, reading.

“You don’t sleep?” Wei Wuxian asked.

“I watch,” Lan Wangji answered.

Wei Wuxian smiled softly. “You’re too good, you know.”

Lan Wangji met his eyes.

“I fell in love first,” he said quietly. “That is all.”

Wei Wuxian’s breath hitched.

Then he laughed. “Well… I don’t hate it.”
