Villainous Senior Sister, You Picked Up the Wrong Heroine's Script

Gu Yu transmigrated.

He even transmigrated into his own book.

He became the male protagonist, followed the original plot to the letter, and worked hard at cultivation one step at a time. He married his beautiful, adorable junior sister, cultivated his way to becoming an Immortal on Earth, and even defeated the villainous Senior Sister, successfully saving the world...

Smack. Gu Yu's dream came to an end.

When he woke up, there was no junior sister beside him. Instead, the Senior Sister, who was supposed to be the villain, was right there, gazing at him with hearts in her eyes.

"A Yu, I'm your destined heroine. I will never leave your side."

Then she stayed with him as they worked hard at cultivation, one step at a time. He married her, cultivated his way to becoming an Immortal on Earth, and even defeated the final villain, successfully saving the world.

Gu Yu was dumbfounded.

The Senior Sister forced herself on me. I'm not pure anymore.

Senior Sister, you're the villain. Did you pick up the wrong heroine's script?
