Two broken families. The children of one family have very good grades and are almost always in the top five, but they cannot withstand the quarrels and abuses of their parents. However, the conditions at home are very good, while the children of the other family are not very good and are ranked in the top 50. However, the family is about to be broken up. They are also silent and have no playfulness. The conditions at home are also very good. Both families have a boy and a girl.
Concept: A broken family may be bad, but it cannot be more precious than his/her smile
