The ballad was already the most downloaded song of 2017 in the mid-year chart and it's expected to top the yearly chart when that's unveiled in the coming weeks.
Despite being released back in January, the song is still in the Top 40 of Melon's real-time chart too, proving just how massive it truly is.
Congratulations to Ailee!
