심연 (sim-yeon) means 'abyss'—a deep, dark, bottomless pit. It's a rare and haunting word rarely heard in everyday K-Pop lyrics, giving it a dramatic literary feel.
BTS uses it in the line "깜깜한 심연 속 기꺼이 잠겨" (I willingly lock myself into a dark abyss). This isn't a literal hole, but a vivid metaphor for willingly diving deep into pain and hardship as a necessary step toward growth and resilience. It captures the song's theme of embracing struggle to emerge stronger.
ON is BTS’s power-packed battle cry against doubt, fear, and anything else that tries to pull you down. The lyrics open in a haze of confusion—waking up in a city that feels both familiar and disorienting—but almost immediately the members steady themselves. They look at their own trembling shadows, recognize that pain is inevitable, and decide to face it head-on. With each “Hey na na na,” they pump themselves up, declaring, “If I’m not going crazy, I might as well choose to.” In other words, instead of letting hardship break them, they’ll channel that pressure into explosive energy.
The recurring phrase “Bring the pain” flips suffering into fuel. Storms, dark prisons, and endless falls become training grounds where they sharpen their strength. Every stumble is followed by “dasi ireona” — “get back up again.” By the chorus, BTS refuse to be held down, calling themselves fighters who will not just survive but live and bleed alongside anyone who joins them. The track celebrates resilience, teamwork, and the unstoppable momentum of pushing “on and on and on.” Listening to it feels like strapping on armor with your best friends before charging into whatever the world throws your way.
