Marking their official debut on July 5, 2023, Kiss of Life immediately distinguished themselves in the K-pop industry with their extended play (EP) Kiss of Life. The debut EP showcased the group’s unique approach by featuring solo music videos for each member Natty’s ‘Sugarcoat,’ Belle’s ‘Countdown,’ Julie’s ‘Kitty Cat,’ and Haneul’s ‘Play Love Games’ leading up to their acclaimed title track ‘Shhh.’ Formed by S2 Entertainment, the groups foundation was built upon individual member achievements; Natty gained early recognition as a contestant on survival shows Sixteen in 2015 and Idol School in 2017, later debuting as a soloist in 2020 with the single album Nineteen and signing with S2 Entertainment in July 2022. Julie trained under The Black Label from 2017 to 2020, while Belle established herself as a songwriter for SM Entertainment. Building on their debut success, Kiss of Life released their second EP, Born to Be XX, on November 8, 2023, featuring the impactful lead singles ‘Bad News’ and ‘Nobody Knows.’ The group maintained a rapid release schedule into 2024, unveiling the single album Midas Touch on April 3, followed by the digital single ‘Sticky’ on July 1.
Further cementing their international footprint, the group also announced their Japanese debut with the EP Tokyo Mission Start, slated for release on November 5, 2025. Beyond their scheduled performances and releases, 2025 will see Kiss of Life further expand their discography with the release of the special digital single ‘Kiss Road’ and their highly anticipated fourth EP, 224. Through a consistent stream of impactful music, strategic collaborations, and a rapidly growing global tour presence, Kiss of Life continues to establish themselves as a dynamic and marketable force within the international music landscape.
