My elder sister Yixiu is introverted and cowardly. She is very obedient to her mother at home. She is asked to do many things she doesn't like, which puts a lot of pressure on her. The younger sister Yilin has a rebellious personality and can't stand the obedience of her older sister. She often quarrels with her mother. The mother at home is strong, and the father quarrels with her almost every day, which makes Yi Xiu withdrawn and does not like to talk to others. Yixiu and Yilin live in such a strange family.
