Ancestor at 18: Young Master Su, Don’t Fall in Love, It’ll Cost You

[Mutual Devotion + A Thousand-Year Time Gap] (At first, the leads are at odds. Later, the male lead begins to fall in love, but the female lead remains unmoved. In the end, he learns her identity and submits to her completely.) Sang Man had spent a thousand years underground. She never imagined that one day she would return to the world above, all to stand up for the only, hopeless heir of the Sang family. She had no idea she would have to deal with Su Jinsan, the Su family’s young master, who could be aloof one moment and a silly goof the next, and who went around saying he didn’t want to inherit the family fortune and only wanted to lie flat. Even stranger, that young master of the Su family was inexplicably obsessed with Sang Man from history. He was willing to spend the family’s entire fortune to acquire anything connected to her. What he didn’t know was that the real Sang Man was right in front of him.
