(Quick transmigration + career-driven heroine + no fixed pairing)
A Li was an orphan. After years of hard work, she finally got to enjoy a mansion and luxury cars, only to die suddenly in an accident. For some inexplicable reason, she became bound to a System and was sent to various worlds to win over people who had directly harmed the original host in a past life, or indirectly caused her tragic fate. By earning their affection and accumulating enough points, she could be reborn. In a panic, A Li could think only of getting home.
World One:
Young heir to the chancellor's house X beautiful, ill-fated cousin
World Two:
Wickedly charming crown prince X empress dowager who got lucky
World Three:
Yandere stepbrother X frail younger sister
World Four:
Twins X cheerful, outgoing girl next door
(Some worlds may not feature mutual devotion, so proceed with caution. Though A Li has a System, she isn't all-powerful. Proceed with caution.)
I just came here to read some cool articles about abusing a scumbag and being slapped in the face, but what did I see? A poor little kid who was abused. He was tortured and slapped in the face. He was also tortured.
