Although it is ballad but it is not a love song, it is about facing herself without spotlight and applause completely. I was touched by her willingness to share her vulnerability, so I asked Xiao Han to write the lyrics for her, I hope through "I" we can walk into Tsai's inner world, and feel we are all the same."
