After I Transmigrated into a Book, I Became the Male Lead’s Darling

Yun Shen was a college freshman who died suddenly after staying up all night and transmigrated into the novel he'd just finished reading, Couldn't Become an Immortal, So I Became a Demon. He became Yun Shen, an early-death cannon-fodder character, a sacrifice on the male lead's path to success, and the senior disciple of the Xiaoyao Sect.

“Great, it follows the rule that you transmigrate into a character with the same name.”

But he was a yao, specifically a peach-tree yao who loved wearing pink!

The System assigned him a mission: lower the male lead's corruption value, but don't change the ending where he becomes a demon.

Yun Shen: ...I'm done. I'll just lie flat.

But while raising the male lead, he realized that Chi Jinyu was starting to look at him differently.

“Senior Brother, don't leave me...”

As the plot changed, the male lead lost all thoughts of turning evil. To maintain the novel's balance, the System made Yun Shen the catalyst for his becoming a demon. In other words, it made him die.

Yun Shen died after the righteous immortals discovered he was a yao and a war between immortals and yaos broke out. Then the male lead went mad!

“Senior Brother, you said you'd love me...”

“I'll save you. You will come back!”

Later, Chi Jinyu looked at the new peach-tree shoots in the courtyard and laughed.

“Shenshen, this time, I'll stay with you as you grow up!”
