4NEMO's company and your company decided to choose you and Xiao to do a song together. It was a love song mixed with a bit of sadness. It was supposed to give your fans an image that you and Xiao were going through something.

So, here you both were, in the studio, looking over the lyrics and waiting for the cue to sing. Of course, for Xiao, he had to rap, but whenever you sang, he chimed in for the background chorus.

The lyrics were very thoughtful and, well, sad of course.
