Keeping a beauty in a golden house version:
Yun Hanyi thought he'd caught a harmless little fawn. He wanted to see how it would struggle in desperation, begging and wagging its tail. But in the end, he discovered that he was the prey falling into a trap, one step at a time.
When his martial arts are completely ruined and he's locked in the back courtyard of Sect Leader Lu's golden house with unopenable black iron shackles around his ankles, sipping tea in a rocking chair, he suddenly can't remember which of them is the prey.
One-line summary: A ruthless, merciless demonic lord sets out to win over a sickly, clingy little crybaby from the righteous sect.
