After I Refused to Be Empress, My Yandere Little Sister Set Her Sights on Me?

Main characters: Ling Xiao and Ling Youran

[Game world + gender-bending + soul swapping + a hundred lifetimes of reincarnation + two yanderes + dark themes + crazed characters + imprisonment + mutual firsts + mutual salvation]

Ling Xiao, a boy, transmigrated into a game world and became a soft, fragrant princess. But he was also a major villain.

He could only follow the game's storyline. The rebellious Ling Xiao killed the heroine, Ling Youran, every time and ascended the throne as empress. Since that went against the story, the world collapsed and the empire was destroyed.

System: [You have to follow the plot.]

Ling Xiao: I refuse.

System: [I'll swap your bodies. You have to follow the plot.]

Ling Xiao: ?

Ling Youran: I agree.

Ling Youran: “Sister, you and I are enemies for life...”

When they started over, the two swapped identities. Ling Xiao became the pampered fake princess, while Ling Youran became a true princess raised among the noble families.

Ling Xiao sneered: The heroine's come right to me. I'll have fun with her nice and slow.

But before long, things got out of hand!

Looking at the timid “self” before him, Ling Xiao couldn't help softening. He acted tough but had a soft heart, cold on the outside and gentle beneath.

Ling Youran chased after Ling Xiao every day.

Ling Xiao rejected her with a cold face, accepted her with a cold face, and spoiled her rotten with a cold face.

As he spoiled her, why was she starting to seem a little yandere?

Yandere Ling Youran: “Sister, are you going to follow the plot or not?”

Ling Xiao: “I will. For the rest of our lives!”

A hundred lifetimes of reincarnation, all so we could be together again.
