What is the song that Wu Xin and Wilber Pan sing together?

I believe everyone is fascinated by Wu Xin and Wilber Pan. I don't know if you remember Orfila's singing skills. I remember Wu Xin had several periods of "singing" in Happy Camp. Those who have heard of it must know that Orfila's pentatonic is not complete, but in Let's Love, Wilber Pan wrote a song specially for Orfila. The two of them sang very sweetly and sang a group of people sweetly.

The name of that song also seems to announce their love affair-"It's rare for no reason". From composing music, lyrics to arranging music, Pan Shuai did it all by himself. Wilber Pan said that every lyric is written by Orfila: "It is true that this song was tailored for Orfila from the beginning to the present, so to some extent, it was originally sung for her, which is quite profound in my mind."

Under the guidance of Wilber Pan, "Magic Sound" Orfila has also become a little girl, and her singing is inexplicably beautiful. Maybe this is the power of love. Ha ha ha ha ha. The tacit understanding between two people also seems to indicate their love. It's really "rare and unreasonable"!
