okay the situation is this: their korean name remains as 방탄소년단, with the literal meaning of it being “bulletproof boyscouts”. but instead of having BTS, their international name, being the abbreviation of 방탄소년단- it has become it’s own independent name/brand. it now stands for “beyond the scene” because they want it to have the meaning as “the youth who have opened the door and moved forward”, rather than “bulletproof boyscouts”.
IN SIMPLER WORDS
Their Korean name=방탄소년단=Bulletproof Boyscouts
Their International name=BTS=Beyond The Scene= Youth who open the doors and move forward
