“Sell your soul and get 10 million yuan.”
It sounded like a joke. Or a scam. Or maybe both.

But for broke, overworked university student Yun Hao, who was barely surviving on instant noodles and unpaid rent, it was just another weird online ad.

So, he clicked it.

He didn’t expect a contract to pop up.
He didn’t expect to accidentally sign it.
And he definitely didn’t expect to end up soul-bound to a demon prince who showed up at his doorstep with red eyes, horns, and a smirk that screamed danger.

> “You’re mine now,” the demon said. “You signed the contract. Which means we’ll live together, sleep together, and maybe—fall in love together.”

Yun Hao: “…Can I return the contract?”
Ruin: “Can I return you to the womb?”



Now stuck with a seductive, annoying demon who insists on being his “soulmate,” Yun Hao just wants to break the contract and go back to his normal, boring life.

But the universe has other plans.

Because the closer he gets to Ruin, the more memories from a forgotten past life begin to awaken…
And he starts to realize—

This demon may have loved him for centuries.
And this "accidental" meeting might not be an accident at all.

Yun Hao stared blankly at the smoking pot on his cheap stove, one hand holding his cracked phone, the other smacking the smoke detector with a slipper.


"Shut up, I'm already broke. Don't take my dignity too," he muttered.


A new notification popped up on his screen.


> [Looking for part-time work? Get 10 million yuan fast! Click to apply!]


Yun Hao snorted. "Yeah, sure. Let me just sell my kidney while I'm at it."


Still… the ad stayed there, glowing in the corner.


He was two months behind on rent. His part-time café job fired him last week. His scholarship results were delayed. And he hadn't eaten real food in days.


A digital contract appeared, written in sleek red letters:


> "Soul-Binding Contract – 30-Day Trial Bond"


Reward: 10 million yuan + basic needs provided


Terms: You will belong to the contractor for 30 days. Emotional, spiritual, and physical closeness required. Extension possible.


Warning: Breaking the bond may result in spiritual backlash. Or death. Or mild headaches.


"What kind of crackhead OnlyFans sponsorship is this?"


He was about to exit, but his finger slipped.


A deep vibration pulsed through his phone—and his chest.


It was past midnight. Who the hell would be knocking at this hour?


He opened the door. And instantly regretted it.


A man stood there, tall and unreal—like someone ripped out of a high-budget fantasy drama. He wore a black suit, no tie, crimson eyes glowing faintly under snow-white hair. His skin was pale, flawless, and two sharp horns curved elegantly from his head.


"Oh," the man smiled, stepping inside without asking. "You're cuter than I thought."


Yun Hao slammed the door behind him, panicked. "Who the hell—?!"


"I'm Ruin," the stranger said casually. "Demon Prince of the Ninth Realm. Collector of souls. And apparently…" He paused, leaning in with a grin. "Your soulmate for the next 30 days."


Ruin pointed to the phone still in his hand. The screen now displayed a glowing red heart, slowly beating.


"You've got to be kidding me," Yun Hao whispered.


"I don't kid," Ruin said, already throwing his coat onto Yun Hao's tiny couch. "I just seduce."
