On July 30, 2014, Big Hit Entertainment launched a countdown clock on BTS' official website,[4] and on August 5, they uploaded a comeback trailer on YouTube which featured contrasting scenes.

On October 21, BTS released 19 concept photos of the follow-up song "War of Hormone" through their official Facebook page and Twitter account.

One month later, the remixed version of the "Danger" music video, a collaboration with a Vietnamese singer and songwriter Thanh Bùi, was released.

The follow-up promotion of the album with "War of Hormone" on October 23 started right after the release of its music video on YouTube, during their concert tour.

The band's agency then released an apology about the song, stating that the members felt remorse for anything that could've been interpreted as objectification or misogyny.
