This is a story about friendship. We have known each other since childhood, played together, and were as happy as angels. We promise together, we are as close as sisters. We grew up together and talked about our own thoughts. Going to the same school and living an ordinary life happily. As people grow up, their hearts also grow up. As people change, so do their hearts. Later, there was a quarrel. Later, we never met again. ． ． ． ． ．
