"UN Village" was released on July 10 for digital download and streaming in various countries by SM Entertainment, as the lead single of City Lights.
[4] The lyrics are about a romantic moment a couple shares under the moonlight of UN Village hill in Hannam-dong, Yongsan District, Seoul.
She added that "Baekhyun takes his time to build up effortless and intricate vocal runs but it’s still just a small taste of what his voice is truly capable of".
[5] An accompanying music video for "UN Village" was uploaded to SM Entertainment's official YouTube channel, simultaneously with the single's release.
The video features a colored and black-and-white theme of the singer while he roams around the titular neighborhood emoting his feelings as he sings.
[11][12] Before the official release, Baekhyun held a private showcase in Seoul Arts Center where he performed the song for the first time for the media.
