Li Weiwei is the neighbor of the Wang family, and she is the same age as her brother Wang Ningyan. As far as Wang Ning can remember, this beautiful and gentle elder sister has been inseparable from her brother. Of course, they are not the younger brother who is several years younger than them. Whenever the school holidays are on vacation, they will take this younger brother with them when they go out to play secretly. So Wang Ning, who is still in a ignorant age, has always longed for this beautiful and gentle elder sister since the beginning, and even hid that her brother had secretly told Li Weiwei that she would marry her as her bride when she grew up.
