After the Naïve Airhead Transmigrates into a Vicious Supporting Character

Su He wakes up to find himself inside a novel—specifically, as the fake young master of a wealthy family, and even worse, the cannon-fodder villainous side character in a melodramatic business war plot!

In the novel, after the fake young master is kicked out of the family, he turns dark and joins forces with the villainous boss, becoming a major obstacle in the male lead’s path to power—only to be heartlessly discarded in the end.

Su He: Huh? A scheming villain who steals trade secrets? Me? (O.O)

To survive, Su He is planted beside the male lead, Sheng Jingyu. By day, he works hard to prove himself a loyal employee. By night, he resumes his old craft—writing diligently as a fanfiction author.

Star racer Sheng Jingyu is a cool guy with a fiery temper and a suspicious nature. After an unexpected injury, he’s forced to return home to inherit the family business—and is saddled with an annoying little follower.

Said follower looks soft and harmless like a steamed bun, but ever since Sheng Jingyu awakened to the fact that his world is a novel, he knows Su He is actually a scheming snake in sheep’s clothing.

Sheng Jingyu: Good. The moment I catch a slip-up, he’s dead.

But no matter how he pressures or entices Su He, the guy never breaks character—always mild, polite, and obedient at his side. Worse yet… he’s even a bit attentive.

One day, Sheng Jingyu stumbles upon a handwritten love letter that Su He "accidentally" left behind. Everything suddenly makes sense. He confronts Su He with a frosty expression, waiting for an explanation.

The little sidekick blushes, eyes darting, and stammers, "It… it wasn’t meant for you."

Sheng Jingyu’s face darkens even more. "Then who were you writing it to?"

Su He opens his big eyes and earnestly says, "Actually… I’m a writer."

Sheng Jingyu is both furious and amused. Secretly crushing on him wasn’t embarrassing—but coming up with such a terrible excuse?

After some thought, the prestigious young master decides… maybe Su He deserves a chance.

As Valentine’s Day approaches, Sheng Jingyu receives a secret invitation from Su He. He coolly agrees, secretly preparing a ring.

Only to arrive at a movie press conference, where Su He—attending as the original author—cheerfully hands him a piece of merch with the now-familiar, signed love letter printed on it. "Thanks for coming!"

Sheng Jingyu stares at the familiar letter in his hands, expression mu*derous.

Then the plot reaches its climax. To avoid disaster, Su He flees in the night—but is swiftly caught, thrown onto a bed by a furious Sheng Jingyu. The big bad wolf closes in, the little lamb stumbles back.

Sheng Jingyu growls, "Run again and I’ll…"

Su He trembles in fear: "Break my legs? QAQ"

"…I’ll kiss you to death."
