After Transmigrating Into a Book, I Ended Up in a Wild Relationship with the Big Villain Senior Sister

Yandere Cold-Blooded Senior Sister x Drama Queen White Lotus Junior Sister

(Dual female leads, system, angst + comedy. The heroine appears to be a tough and unyielding white lotus, but in reality, she’s a heartless acting expert.)

Ling Yin stayed up all night reading and suddenly died of exhaustion. She woke up to find herself transmigrated into a character with the same name as her in the book—a malicious white lotus junior sister who, out of jealousy for the male lead, repeatedly tried to harm the heroine. In the end, she was imprisoned and tortured to death in the demon realm dungeon by the villainous senior sister, who loved the heroine but could never have her.

After that, the villainous senior sister completely descended into madness due to her unrequited love and shattered memories. She activated a world-destroying formation and blew up the entire world.

System: “Your mission is to redeem the villainous senior sister and stop her from destroying the world!”

Ling Yin: “Can I not do that?”

System (coldly): “You’re already dead. The only way to go back is to complete the mission.”

Ling Yin could only grit her teeth and charge ahead.

But can someone tell her—

Why did she wake up already locked in the dungeon?!
