Xie Yunfan, on the surface, is the adopted son of the top wealthy Xie family, but in fact he is the official heir who lives among the people. Five years ago, he was framed and his reputation was ruined. He was forced to leave the Xie family with his infant daughter. Five years later, he returned with his daughter, only to find that the Xie family had recognized the so-called "real daughter" - a fake. What's even more ironic is that this fake daughter imitates his yandere character in every aspect, but fails to turn out to be the opposite of a dog. Xie Yunfan is gentle and gentle on the surface, but in reality he is ruthless. He uses his identity as a nanny as a cover and secretly plans to make everyone who has hurt him and his daughter pay the price. Daughter Xie Xiaotuanzi appears to be innocent, but in fact she is extremely precocious and is her father's most effective "little helper". When the truth gradually emerged, and the mastermind of the conspiracy finally appeared, Xie Yunfan found himself trapped in an even bigger whirlpool - his daughter seemed to be hiding an even more astonishing secret...
