This ballad reminisces, both in the title and lyrics, the time taken to master a skill, or in this case, truly fall in love. The Soundcloud link of the song has the words ‘10000hourswitharmy’ in it, what indicates that the song is for and about ARMY (BTS fans).

Originally the song was posted on BTS' Twitter account as a video. The short clip highlighted Jungkook’s take on the first 49 seconds of the original song. Later it was deleted and re-posted as a Soundcloud link to full cover.
