[Fragile-Looking, Violent Top] [Rich, Willful, and Dotingly Indulgent Bottom]
Si Yuxuan comes across a lost young man. The boy is beautiful and naive, seemingly inexperienced in the ways of the world. He has come from a remote mountain wilderness so poor he doesn't even have an ID card.
The boy's eyes shine with tears as he says he wants to repay his kindness.
After thinking it over, Si Yuxuan decides the boy is far too pitiful to send out into the world, where people would surely bully him. So he decides to take him in for now.
The boy is exceptionally fussy. He'll only eat freshly picked food, drink milk from a particular region, and eat freshly baked cake.
Si Yuxuan doesn't mind.
He's always spoiled the boy, because he thinks the poor thing is so helpless that he wouldn't survive without him.
Then one day, he sees with his own eyes the exquisite, otherworldly boy sprout black wings from his back, his eyes turning into blood-red jewels. With one hand, the boy crushes a monster trying to devour someone, a murderous chill in his expression.
Confused, Si Yuxuan shuts the door. When he opens it again, the boy is still there, smiling sweetly at him, as obedient as ever.
Nan Deng thinks he's lucky to have met a good person as soon as he came out. This man takes him out to eat, helps him bathe, and even gives him clothes.
The elders once said humans were easy to fool. Nan Deng couldn't agree more, and does everything he can to stay by this man's side.
The man's scent is like the spring passion flower he loves most in the abyss, making him want to claim him for himself.
Unfortunately, there are always fools who interrupt his enjoyment. No matter. If one comes, he'll kill one. If two come, he'll kill them both.
Seems he's been asleep for far too long. Even cats and dogs don't remember him anymore.
Nan Deng runs his tongue over one sharp little fang and smiles innocently. "Oh no, people are about to forget the name of the Great Demon King."
