Dasvidanya means goodbye in Russian. This is a story that uses love to interpret an ideal that cannot be realized. It is a slightly regretful work. But the regret is that we will continue to come into contact with and grow as we grow up, and it is also realistic. The story begins in our most confused and hesitant college days, which is also the age of youthful struggle. But the story does not end, because a thousand people have a thousand opinions on the story and will give it a thousand endings, so the real ending lies in the readers' hearts.
