The Ning family and the Jing family are family friends, and Ning Suyi is only two months older than Jing Chi. The two grew up together, and they can't be called siblings. But Ning Suyi always relies on himself when teasing Jing Chi. Born dozens of days earlier than him, she often considers herself an older sister, and her brother and brother keep barking. Brother, do you want to eat egg yolk? I won’t eat it. Brother, why don’t you find a girlfriend? Brother, I found that you don’t smell like medicine anymore ... (Jing Chi was often ill when he was a child, and his body smelled very good of Chinese herbal medicine) Every time Jing Chi heard Ning Suyi's name, he would be so angry that he thought who would be your younger brother, I want to be you Boyfriend!... Later, when the two were together, Jing Chi held Ning Suyi's waist and whispered in her ear: Sister, you look so cute when you are angry. Covering his mouth tightly, with great strength, as if to choke him to death: Shut up, shut up, shut up! Don’t call me sister again!! Do you hear that?! As soon as this person calls her sister, she will be damned There is a sense of guilt. Jing Chi begged for mercy with innocent eyes, but after she let go of her hand, she reverted to her old ways: No. Sister... Jing Chi: The happiest thing for me is to be able to protect my sweetheart and grow up slowly. How lucky I am , I have seen her crying when she was a child, and I have also seen her smiling like a flower when she grows up.
