Su Fuying has an older brother and two younger brothers. Her future husband lives in the house next to her.
Her brother is much older than her and cannot play with her. Her younger brother was not born when she was young and cannot accompany her. Only Fa Xiao (future husband) who is the same age as herself is different.
If she cries because she is hungry, Lu Wensheng will give her what he has on hand. If she cries because there are no toys, Lu Wensheng will buy her with his pocket money. If she cries because she cannot do well or finish her homework, he will teach her.
Of course, Su Fuying would also accompany Lu Wensheng when he was unhappy, giving him a lot of emotional value, including the basketball he wanted to buy or the game console he wanted to buy.
