Quick Transmigration: The Ultimate Heartbreaker

After binding herself to a System, Miao Yu spends every day nervously dreading a warning that she's about to break character. Not only that, she's also forced to become a heartless woman. To fulfill the original owner's unfulfilled wish, or perhaps to indulge the System's twisted sense of humor, she has to win the hearts of her conquest targets... and then dump them. But the targets in these worlds are obsessive and yandere, and she feels like her little heart can't take it.

System: I'll give you a golden finger. Don't be afraid.

Miao Yu: I'm worried I'll kick the bucket first.
