The Villainess Is Doted on by a Brooding Tycoon Until She Becomes His Little Ancestor

After Tang Suisui died in a car accident, she transmigrated into a Mary Sue world.

Before reaching adulthood, she was suppressed by the will of the world. She had three Systems, yet could only play the part of a vicious supporting female character.

System No. 1, Miracle Suisui, is a knockoff of Miracle Nikki. All it can do is let her change clothes. And then change clothes some more.

System No. 2, nicknamed Motherly Care, has only one use: knitting sweaters.

System No. 3 has yet to wake up.

On the day she came of age, Tang Suisui faced her childhood friend, whom she'd "loved" for over a decade, and who would eventually stab her to death for the Mary Sue heroine. She picked up the cake and smashed it into his face.
