What is the name of the sad background music in Princess Zhu Huan Part III?

I know that there is no pure music in that song on the Internet, only pure music is converted into musical words. The title of this song is "Most Afraid of Parting". There are lyrics fragments sung by Wei Zi and pure music fragments, that is, ah, ah, ah, ah, ah, ah, ah, ah, ah, ah, ah, ah, ah, ah, ah. There is hardly this song on the home page of princess huanzhu 3 on the internet. Call out all the songs to be searched and the singer Liu Pan (Cool Dog Music). I searched for information all afternoon before I found it.
