A wild, arrogant top who can't bring himself to act that way toward his wife x a naive, socially clueless but utterly frank bottom
Yun Henli was born with a heart of glazed crystal, formed from the ancient divine artifact Liuli. With ancient divine power from birth, he had a talent for cultivation that everyone envied in this world, where spiritual energy was scarce.
But Yun Henli had cultivation on his mind and nothing else. He knew nothing of social niceties, and other people's trivial affairs could never distract him.
That changed when he met Duan Yu, who also carried ancient divine power. Yun Henli found himself drawn to the other man. First, he agreed to move in next door to Duan Yu. Before long, he was sleeping in Duan Yu's bed.
During his time with Duan Yu, Yun Henli broke through the limits of his cultivation and found the love of his life. Lost in happiness, he still had no idea that a catastrophe was about to befall the world, or that he was about to become a man burdened with a priceless treasure.
As the emperor's younger brother and a man with divine power, Duan Yu had always led a smooth and fortunate life. He was arrogant by nature. Then, three years ago, his fiance disappeared just after Duan Yu proposed. Not a trace of him could be found anywhere in the world.
At long last, they reunited on a battlefield. Yun Henli was at the head of the rebel army, laying siege to the city.
Duan Yu had planned to capture the rebel leader and then keep Yun Henli under house arrest. He never expected Yun Henli to look at him as though he were a stranger.
Duan Yu was so furious he nearly spat blood. Fine. Just fine. Absolutely wonderful!
[Bonus Scene]
After Yun Henli woke up, he heard Duan Yu say:
"You're my prisoner now."
"Oh."
"Don't you have anything else to say?"
"I'm cold, Duan Yu."
Duan Yu's face stiffened. He decided to become a hot-water bottle who would never again warm Yun Henli's bed with a smile.
One-on-one, both chaste, happy ending
