"Tiānshǐ Mèng" is an original Xin Hua song. Xin Hua keeps catching glimpses of an angel while going about her daily life. However, every time she sees it, she dismisses it as a dream or uses other excuses, such as telling herself that it was just a nice cosplay. Towards the end of the song, as she keeps dreaming of the angel and she comes to realize that she actually knows them. Just as she recalls the memories of events that happened between them, they were separated again.
