I was definitely not expecting this collaboration but hot damn! They beat and killed it. This was such an awesome pair. My girl Ailee with my baby boy Niel, a match made in heaven. And holy ! That "kiss" at the end. I ship Nielee (the OTP name I came up with)

(I would've been a whole lot more excited though if it was Chunji and Ailee (even though Chunji's voice wouldn't have suited the song) just for the simple fact that "Jaeyeon" in my story A Thousand Reasons to Cry is played by Ailee and my Jaeyeon x Chunji ship would be alive!! Or Changjo would've been amazing too. Omfg, yeah now that I think about it, I would've loved to see Changjo do that collab)
