Background and composition
On March 23, 2024, the second teaser of Japanese television drama Re: Revenge – Yokubo no Hate ni was revealed, alongside an announcement that Stray Kids would perform the theme of the drama, titled "Why?", making it the group's first Japanese drama series theme. The song became available for digital download and streaming platforms on April 12, after the first episode's premiere.
