[True and fake daughter + long flowing water + overt and covert temptation + broken life experience + 1v1 double sweet pet]
The Zhuang and Yu families had not been in contact for many years, but a childhood marriage contract brought the two families together.
Zhuang Li is the adopted daughter of the banker, and is hated and feared.
The banker's biological daughter is the heroine in this engagement.
Zhuang Li unexpectedly became the Yu family's tutor. She didn't know that the man she had frequent contact with was the real hero of the marriage.
An engagement is favored by the elders of both parties but strongly resisted by the parties concerned. Under the smooth surface is an extreme dislocation that no one knows about.
