After Reforming the Scum Gong, I Got a Happy Ending with His Ex

[Updates according to the rankings before the story goes premium]

"A seemingly obedient, calculating green-tea type who is actually a scheming yandere top × a seemingly aloof and arrogant bottom who is actually softhearted"

Only after being reborn did Lu Xu realize that he was merely a supporting character in countless stories, while the protagonists were all scum tops who were always one step above him.

He was forced to bind himself to the Scum Top Correction System. His mission was to make the scum tops in each world come to their senses and reunite with the protagonist bottoms.

But...

Do those scum tops deserve them?

He might as well steal all the protagonist bottoms away.

System: "Hey! You're supposed to correct the scum tops. Why are you sleeping with their exes?!"

[World One: The top-tier star's tagalong younger brother × the devoted movie emperor]

The top-tier singer summons the movie emperor whenever he wants and dismisses him just as easily. In public, he hints that the emperor is throwing himself at him, but in private, he enjoys the emperor's devoted care.

Lu Xu is the top-tier singer's cannon-fodder younger brother.

When his brother mocks the movie emperor for losing his figure, Lu Xu anonymously sends the emperor sexy lingerie with a note: "A good figure needs to be shown off, baby. Put it on and take a picture for me."

When the movie emperor is about to visit a hot spring with his brother, Lu Xu corners him in the changing room. Seeing the sexy lingerie faintly visible beneath the emperor's white shirt, he smiles. "Baby, so you wanted to wear it for me in person."

The movie emperor blushes. "I... I like your brother..."

Later, the top-tier star finally comes to his senses and plans to propose at his concert with a diamond ring. But when the big screen switches to the backstage area, he sees the movie emperor, who was deeply in love with him, straddling Lu Xu's lap, his eyes red from kissing and two shirt buttons undone.

"Little brother's a better catch."

"Didn't you like my brother?"

[World Two: The celestial master's errand boy apprentice × the mermaid ruler]

The coldhearted celestial master treats the mermaid king, who loves him deeply, as a tool to prolong his life. Every time he borrows the mermaid's life force, he abandons him without a second thought.

Lu Xu is the lowly apprentice who runs errands for the celestial master.

When the mermaid nearly dies of dehydration after lending his life force once again, Lu Xu takes him to a secluded hot spring paradise. He strokes the mermaid's tail and blinks curiously. "I heard all mermaids have a pleasure spot. Is that true?"

The weak mermaid king turns pale and curses incoherently. "The one I like is your master!"

Later, the celestial master finally returns after overcoming his tribulation, hoping to marry the mermaid. But the mermaid he treated like trash is curled up in Lu Xu's arms, sleeping soundly.

"Young men sure have more stamina."

"Didn't you like my master?"
