Sometimes, for a certain period of time, you will desperately want to keep someone in your heart. But when everything passes, three years, five years, eight years, ten years later, you will find that the imprints in your heart are things that you didn't pay attention to in the past. They are faint, but cannot be erased, and they are always imprinted there. But there was no trace at all of the things I tried so hard to keep.
