I found it baffling that 3 people rated this a 0 as of writing this. They probably think just because it's BTS then it means the song's bad. These people are just as bad as the cancerous K-Pop stans because their preconception made them failed to be fair and just in assessing the song.
But anyways, the song is great. Despite the corniness of the song at some points, it's emotionally effective and one of the group's best songs yet.
