"That desert I was once afraid of became an ocean from our blood sweat and tears"
BTS always has moving lyrics, but I really connected with the words in their hidden track SEA (thank you@sinisterbangel for posting it!)
In the song they talk about how when they started out it seemed dismal. They were a small company, they sounded and looked different, and there were endless hard times.
Then, by their hard work, literally their blood sweat and tears, they turned the desert of failure into an ocean of success.
