So I saw a Chinese MV a few months ago and really loved the song and had saved it in a YouTube playlist of mine. I didn't listen to it for awhile and when I went back to hear it again I found that the video had been removed from YouTube and the song title was unfortunately gone as well. Now I have no idea what the song or artist's name is but I hope someone could possibly help me figure it out because I'm going crazy trying to find it

All I can remember from the MV is that the male singer had a very thin, high voice and the song is a mix of traditional + rnb sound and the story was about a girl in white dress fighting a man in black costume but ended up loving him in the end. I think the singer was also playing a gu zheng, not quite sure about that part though. If anyone has any guesses, please post! It would be much appreciated
