On September 25, BTS released a comeback trailer on YouTube, featuring member J-Hope rapping solo. The video depicted a boy's mind meeting a devil called 'temptation'. From September 28 to October 4 Big Hit Entertainment released concept photos of the album on official Instagram, Twitter, and Facebook pages revealing the album will be available in four physical versions designated: W, I, N and G. The album's track list was then released on October 5 on the official website and Twitter account. A music video teaser was also released on October 7 on YouTube, indicating "Blood Sweat & Tears" would be the lead single. Big Hit Entertainment lastly revealed the design and details of the physical album which would include a photobook, polaroid, mini standee and poster.

During the press conference for the release of the album, leader RM explained, "The harder a temptation is to resist, the more you think about it and vacillate. That uncertainty is part of the process of growing. 'Blood Sweat & Tears' is a song that shows how one thinks, chooses, and grows." Symbolism such as the 'wings' were representations of growth, with Suga adding, "The song relays an optimistic determination to use our wings to go far, even if we are met with temptations in life." Jungkook explained during the group's preview show on V Live, that his solo track, "Begin", was about his journey to Seoul and meeting the BTS members. V described his song, "Stigma", as "a song under the neo-soul genre". J-Hope described his song, "MAMA", as unforgettable, as it was about his childhood emotions for his mother. "Awake" was Jin's first experience in co-composition. RM revealed the 14th track, "Two! Three! (Still Wishing For Better Days)" ("둘! 셋! (그래도 좋은 날이 더 많기를)") was the first official fan song. The song "Am I Wrong" samples Keb' Mo's 1994 jazz/blues song "Am I Wrong" and the album credits Kevin Moore as co-writer and co-producer.
