Description：Sheng Qin (Alia)'s father, Mr. Sheng (Wang Deshun), suffers from Alzheimer's disease and his condition deteriorates, and he eventually becomes unable to take care of himself. In order to take care of her father's daily life, Sheng Qin hired a nanny named Mianhua (Yan Bingyan). Although Mr. Sheng's memory is fading every day, the only thing he can't forget is his wife who has passed away for many years. Not long after Mianhua took office, he was repeatedly mistaken for his wife by Mr. Sheng, causing a lot of trouble. Sheng Qin also questioned Mianhua's character. As time went by, a special trust was established between Mianhua and Mr. Sheng, but at this critical juncture, Mianhua was pregnant. The devastated Sheng Qin suspected that the child in Mianhua's belly was her younger brother, so she secretly launched an investigation, which also involved Mianhua's secret hidden for many years.
