The Wicked Female Side Character at Five and a Half

Xu Yuanyuan grew up cherished by her whole family, a sweet little darling. One day, she wakes up in a strange place.

A System in her head tells her she’s a fake heiress, and that she must drive the real young master out of the Xu family before she can see her parents again.

But… the real young master is a handsome older brother.

After spending half his life struggling in the mud, Xu Yan is reborn.

His first move is to return to the Xu family and deal with Xu Yuanyuan in advance, before she can torment him like she did in his past life.

But Xu Yan discovers that the once arrogant and domineering Xu Yuanyuan is only five and a half years old this time. And five-and-a-half-year-old Xu Yuanyuan is a bit of a dummy.
