Composition
The EP consists of seven tracks consisting of various genres ranging from trap, hip hop, nu-disco, and R&B. The band stated that they wanted to show their masculine side and be real men. Speaking of the album's black and red colors, Eunhyuk states that the former symbolizes charisma, while the latter is "sexiness." Donghae recounted the inspiration to write the EP came from horse racing, and invites the fans to run alongside them without looking sideways.

The opening track, "Danger" is an electro house song with trap influences to bring out the charismatic personalities of the members. Penned by Donghae and J-DUB, the song featured dark sounds with minor chord progression with its lyrics playfully likening the expression of "ding" as "danger." "Jungle" is a trap song with strong synthesizer sound, reminiscent to a jungle. The lyrics were written as a first-person who sees everything.

"Gloomy" is an R&B song with an 808 bass sound and a somber electric guitar melody to amplify the song's emotions. Its melancholic lyrics were penned by Donghae. The music video for the track was released on April 12, two days before their Seoul concert, and it was directed by their bandmate Shindong. "Watch Out" is a pop song with a groovy rhythm with its lyrics warning the listeners during one that fell in love with someone dangerous. "Dreamer" is a pop ballad song with mellow melody and a dynamic burst of sound in its chorus. The lyrics sympthasizes with someone suffering from anxiety. The track was written by Tha Aristocrats, the production team behind labelmate Exo's "Overdose."

The EP concludes with the Korean versions of "Sunrise" and "If You", the tracks that were previously released in Japanese.
