Su Chun has always felt that the airport is the place with the most tears in the world. She has been flying to and from various places since she was a child, so she has seen many people hugging each other and crying at the airport. Some are because of the joy of being together, and some are because of the pain of separation. But isn't that what life is like? Who can guarantee to accompany you through this long journey? Some people accompany you for a while, and when you reach a fork in the road, you find that your destination is different, so you wave goodbye and turn around to go on a different journey. You never know who you will meet along the way. The joy of life sometimes has no unknown way forward, so Su Chun loves traveling not only because of the scenery on the road, but also because of the unknown experience.
