A flirtatious, roguish top who seems wicked but is pure at heart VS a sharp-tongued bottom who seems proper but is wicked at heart
Demon Lord Xue Renhan is a notorious womanizer, alluring and wickedly charming. He is a vicious menace feared by every sect in the cultivation world, quick to take offense and brutal in his methods.
During the war between the immortal and demon realms, he falls in love at first sight with Pei Junchu, the young master of an immortal sect, and vows to make him one of his consorts.
Everyone calls him a shameless scoundrel, deluded and utterly without hope. He narrows his eyes and smiles wickedly. "Then just wait and see."

On Pei Junchu's wedding day, Xue Renhan storms the immortal sect with his followers. He forcefully presses the head of the badly injured Pei Junchu down in a kowtow, then points at his family and asks coldly, "Whether you marry me isn't up to you. Tell me, who should I kill first?"
After one night in the bridal chamber, Pei Junchu is forced to give in and taken back to the demon realm. Everyone assumes he's doomed: beaten every three days and starved every five. But Xue Renhan dotes on him, cherishes him, and even lets himself be dominated...
He does everything he can to please him. "A Chu, among all the people in the world, only you satisfy me."
"A Chu, I love you. I'll give you anything you want."
Pei Junchu always responds with vicious insults. "Xue Renhan, you're utterly disgusting, shameless to the extreme!"

Xue Renhan dotes on and protects him, thinking he will eventually win his heart. Until the day the demon realm is massacred and rivers of blood flow. Seeing the innocent young demons lying dead, and Pei Junchu standing among the immortal sects with an air of righteous indignation, Xue Renhan finally understands what is in his heart.
Even a cruel, bloodthirsty man like him is in such pain that his eyes turn red. "Pei Junchu! No one can match you when it comes to being heartless. Fine, today you can have it your way!" With that, he detonates himself before them all.
Pei Junchu breaks through the forbidden spell and spits blood. He attacks the others in a frenzy, then collapses, trembling as he clings desperately to Xue Renhan's body. "Xue Renhan!!! I like you! I really do like you!!"
Later, word gets around that Pei Junchu went mad for a long time, completely fell to the dark side, and became the nightmare of every immortal sect.
Until one day, he sees Xue Renhan dressed in white, with a man who looks like a refined courtesan in his arms. Gritting his teeth, he asks, "Renhan, who is he?!"
Xue Renhan curls his lip into a smile. "My 360th consort. Is there a problem?"
Content warnings:
1. An unconventional groveling arc.
2. The bottom has previous partners early on and had a harem, but disbanded it all after getting together with the top.
3. Happy ending, bittersweet romance. I love you, you don't love me; you love me, but I think you don't. Neither of them is a bad person.
