Title track, "I Know It's a Joke", expresses the emotions of a woman who finds herself in denial when she is suddenly asked to break up by her boyfriend.

Her agency Pledis Entertainment rep stated, "As much as this is Raina's 1st solo album, we worked hard to bring out Raina's real hidden vocals... Raina's vocalices and Kanto's baritone rap also helped bring out the song's lonely emotions. Please look forward to their chemistry."
