Many years later, I still dream about the boy who frowned and thought about the problem when he was doing the questions. I thought that after a long time, love would turn into a family relationship that we get along day and night, and that after a long time, resentment would fade away due to no contact with each other, but I found that after so many years, those who have accompanied you through youth, whether they have hurt each other or loved each other deeply, will suddenly bubble up one day after being silent for a period of time, forcefully pulling you back to the depths of time. Whether you are willing or not, those old times and people deep in your memories are there.
