Li Jinnian, who had his biological mother protecting him, did have a carefree time when he was young.
Later on, when his biological mother passed away, Second Old Madam Li's true colors were revealed. A child without their biological mother's protection became as lonely as a blade of grass. Second Old Madam Li made sure to weed him out. Less than half a year after his biological mother passed away, Li Jinnian's smile disappeared.
Fortunately, he was smart. The somewhat mature child could see the fierceness hidden underneath Second Old Madam Li's kind face. In addition, he would suffer in front of Du Jiayi and her brother from time to time. Li Jinnian's personality got colder and colder, and he became more and more reticent.
Until his biological father married Second Old Madam Li, Li Jinnian would only show his face when he ate at home. The rest of the time, he would lock himself in his room.
