The first track, "Dinosaur" marks AKMU's first attempt on electronic dance music genre. Lyrically the song talks about waking up from nightmare of a dinosaur and fighting against it. It is based on Lee Chan-hyuk's childhood memory of similar real-life incident. Tamar Herman of Billboard explains that AKMU's "nostalgic approach to dance music... showcases a new side to the Lee siblings in a way that still retains the wholesome AKMU charm." The second track, "My Darling" was described as an "acoustic song with cute lyrics with repetitive hooks and easy melodies".
