I think the world isn't giving BTS enough credits for their incredible storytelling through cinematographic music videos and hauntingly beautiful from their honest emotions, hearts on their sleeves, that even something that is fundamentally monotonous & painful, can be beautiful.
bts adding this is VERY important. merry go round emphasizes that while you may feel you are moving forward in life (growing up, achieving success) you are still anchored to the same heavy anxieties. the horse vertical movement mimics life’s temporary highs and lows but the horizontal trajectory never actually leaves the circle. growing up does not mean being free from anxiety and pressure. this is bts telling us that you are NOT alone when it comes to that kind of struggle.
