Kiss of Life (; stylized in all caps), also known as KIOF, is a South Korean girl group formed by S2 Entertainment in 2023. The group consists of four members: Julie, Natty, Belle, and Haneul. They debuted on July 5, 2023, with the extended play (EP) Kiss of Life.
Name According to S2 Entertainment, the name signifies their ambition to "breathe a new life into the music industry with their music and charm." Reflecting on their name, the group's concepts revolve around the different stages of life, adolescence and young adulthood.
History 2015–2022: Pre-debut and formation Belle is known as the daughter of the veteran Korean singer Shim Shin. She used to work for SM Entertainment as a songwriter. Natty was a contestant on the South Korean reality survival shows Sixteen and Idol School, that led to the formation of Twice and Fromis 9, respectively. In both shows, she made it to the final episode, but was ultimately not chosen for the final line-up of both groups. In 2020, she debuted as a soloist with the single album, Nineteen. Julie was a trainee under The Black Label, a sub-label of YG Entertainment from 2017 to 2020.
On July 12, 2022, Natty signed an exclusive contract with S2 Entertainment. In December 2022, Natty was featured in a British documentary about K-pop trainees along with Julie, Belle, and two other unknown trainees. It was speculated that they were the alleged members of the company's upcoming girl group. On December 27, S2 Entertainment announced they were preparing to launch a new girl group in 2023. Later in February 2023, it was discovered that the agency had applied to trademark Kiss of Life and that they had opened SNS accounts of the same name for the group.

In April, Kiss of Life shared videos to celebrate Julie's birthday with the theme "old-school hip hop vibes". In a live broadcast, members wore gold chains, gold hoop earrings, snapback hats, and cornrows. Members gave themselves nicknames, including referring to Belle as "Lil Taco Belle". They mimicked African American Vernacular English and used exaggerated mannerisms "commonly associated with stereotypical portrayals of African American rappers". The videos were criticized as culturally insensitive and representing cultural appropriation. The videos were deleted and the members of the group issued apologies. Following the controversy, the group lost about 200,000 followers on Instagram, going from 3.7 million followers to 3.5 million followers. The group later withdrew from a planned performance at KCON in Los Angeles, citing a mutual decision between the group's agency and the event promoter. In a statement released in June, S2 Entertainment reiterated their apologies for the video and stated they would "take all necessary legal actions" regarding death threats, misinformation, sexual harassment, and deepfakes against the group.
On May 7, Kiss of Life released a special digital single "Kiss Road", with the lead track "Live, Love, Laugh". On May 19, it was announced that the group would be releasing their fourth EP 224 on June 9. On November 5, Kiss of Life made their Japanese debut with the EP Tokyo Mission Start, which is supported by their first original Japanese song "Lucky", and the Japanese version of their single "Sticky".
In 2026, Kiss of Life embarked on their Déjà Vu fan meeting tour in Asia. On April 6, Kiss of Life released Who Is She, their second single album. Their third single album Sweat was released on August 4.

The members additionally mentioned that they listen to a lot of R&B and hip-hop music, being strongly influenced by artists such as Ariana Grande, SZA, Rihanna, and Rosalía as well. Individually, Julie cited Blackpink and 2NE1 as her role models, Natty cited BoA and Yerin Baek as her role models, Belle cited Sabrina Carpenter as a musical inspiration, and Haneul cited Olivia Rodrigo as her role model.
