Graduation season is here again, do you still remember that boy in white? If the love we had in the past didn't bring us together, will there still be an attraction that goes off the rails of life after the passage of time? This is a story about everyone growing up. When you step outside the ivory tower, it is not just as simple as learning to put on a tie and high heels. Only an evenly matched love will be wonderful. Finally, this is a love letter to my beloved Beijing.
