Su Ran, a music prodigy, woke up transmigrated into a book.

At that point in time, the main story arc in the book had already been completed. As a villainess female supporting character, not only did she need to take over the original owner’s pitiful life in poverty, she also gained an instant son right at his rebellious period.

Ten or so more years from then, the son would turn into a twisted, evil villain. He would appear in one of the extra chapters to pick on the male and female lead’s children.

Su Ran: Son, you shouldn’t be too outstanding.
Su Han: Why not?
Su Ran: ’cause you will be killed.

Su Ran: Son, would you like to learn music from me and become a zen, little fairy boy who only needs to drink dew.
Su Han: No, I want to go into business so I can support you.

- Description from Novelupdates

Rise Lee, a well-known A-rank esper in the federation. He was even ranked as one of the strongest among the A-ranks and recognized as one of the hopes for humanity. However, he wasn't only famous because of his prowess or his attractive appearance; Rise was more infamous because of his terrible personality. He was called a villain by most guides and espers for a reason.And who would guess that Rise Lee was really a villain, in a literal sense? The terrible truth then unfolded to him. He, Rise Lee, is one of the main villains of the novel. Rise Lee spat out a mouthful of curses and swore that if he had a second chance, he would mess up this damn novel until everyone went down with him. If the author was in front of him, he too would be destroyed with him! And a second chance did come! Rise Lee, the villain, woke up five years before the main storyline! Heh. So what if he was a villain destined to die? That protagonist who killed him, and the author... He would screw them over. Being a villain, be damned. In this rebirth, he would take and mess up everything. What did you say? The protagonist’s love life? Heh. That too. Rise would take his lover. The male lead... will be his.

To exact revenge on her fiance who cheated on her, Xing Shu plotted against her fiance’s uncle, Cheng Lang. “Was my nephew unable to please you?”

On a large, messy bed, Cheng Lang pinched Xing Shu’s chin. The black Buddhist bracelet around his wrist swayed from side to side. Everyone said Cheng Lang was a religious man who stayed away from women.

However, after sleeping with him for a night, Xing Shu expressed how it was actually easy to manipulate him. She only needed to say sweet things to him in a soft, gentle voice, and he’d give her anything she wanted.

“Mr. Cheng is only putting on a show with Xing Shu. He’ll dump her very soon!”

“Xing Shu is a shameless woman. Mr. Cheng would never fall for someone with ulterior motives like her!”

Everyone in Jing City waited for her to make a fool of herself, but nobody knew how Cheng Lang pinned her against the bed at night. “Xing Shu, mention getting a divorce again if you dare.”

Ever since then, Cheng Lang, a man who once belonged on the altar, was brought down by Xing Shu. He experienced what it felt like to be in a relationship like a normal person, and he found joy in it.
