BTS's RM and V revealed their 14 years of teamwork and music production process. In a recent video released on the YouTube channel 'BDNS,' the two mentioned a promise they made during their military service and talked about the team's unwavering bond over a long period.

RM explained that consideration and love among members, as well as the desire to convey something to their fans, sustain BTS's unity. He expressed his affection for the team, saying, "It is not easy to stay together for 14 years without a single member leaving." He added, "I am truly moved."

He also spoke specifically about the music production environment. RM described the work process in LA, stating, "We worked six days a week." Regarding the studio layout in LA, he said, "Usually, when you think of a studio, you imagine a recording room in the basement of a building, but in LA, there are several buildings outdoors." He explained, "Each building is a studio," and mentioned that they used four rooms simultaneously for two months. About their working method, he said, "We would all exercise together in the morning, and from 2 p.m. to 8 p.m. after lunch, we worked in our respective rooms with songwriters and producers."

RM revealed that he archived over 100 songs in two months and selected 14 of them to work on.

Currently, BTS members are keeping the promise they made during their military service, continuing their music production and teamwork.
