Love is an eternal topic. But when we really put it into ourselves and experience the ups and downs, we realize that love is really not just a simple word. I am Changliu. I have a secret love for a boy I have not seen for a long time. Until I am about to graduate from college, I find him again. Will our love really have a happy ending? Love, in the years, what kind of tempering does it need to go through before it can have a happy ending?
