In February 2017, Suho said members were planning to actively promote themselves in 2017, kicking off during the Korean summer of that year. To publicize the group's comeback to social networks, official pages were created on Facebook, Instagram, Twitter and Weibo, where they released the teaser previously released during the SM Town Live World Tour VI tour and the other individual teasers. On Twitter, the group used Instant Unlock, which allows users to watch videos and special content to spread it. To gain access to the video, it was necessary for site users to choose a hashtag ─#EXO, #KoKoBop, or #TheWAREXO─ and tweet about it, making it a trend worldwide.
