The Spoiled Young Master of Lord Xiao

The title can't be changed now that I've signed the contract. Also known as I Reel in the Big Shots Across the Stars

Both are inexperienced; both are strong; the pursuer absolutely spoils the pursued and has a powerful possessive streak. Once they get together, the pursued gets a bit possessive too.

Delicate young master Ji Yu, the pursued × scheming big shot Shen Siyi, the pursuer

Ji Yu transmigrated into a book and became the fifth young master the Ji family had finally found. To avoid meeting the same ending as in the book, he decided to latch onto someone even more powerful than the protagonist, then pay them back by bullying them mercilessly. But why was this System that had appeared out of nowhere telling him to reform the villain?

Still... this person was exactly the powerful backer he was looking for! He'd accept the task, just this once! But why did the task turn out to be different from what he expected? And why was the villain's gaze getting more and more unsettling...

Lots of side couples
