This is an emotion that carries different girls. There is joy and sadness, and it is recorded from the perspective of others. There are enemies who love each other but cannot love them, there is a girl who wishes the boys well and they grow up together, but their families object and they move away. There are scumbags, but there are also mutual healing. The author is not a primary school student, so he adapted it from events he has seen.
