Yan Chu: The days when we wore crotchless pants together when we were three, the days when we went to and from school together when we were seven, the days when we did homework together when we were thirteen, the days when we skipped class together to chase girls with you when we were seventeen... It wasn't until I saw you confessing to another girl at the age of twenty that I realized that I had been forcing you to stay by my side during the years we spent together. But even though I knew that forcing things would have no end, I still couldn't control my heart, so I chose to leave.
Xu Lang: You have been by my side since I was a child, like air. I can't see it, but I can't lose it. I'm sorry, I understood it too late.
