MSG Wannabe is a K-pop and R&B supergroup assembled through the MBC variety show Hangout with Yoo in 2021. The group is divided into two subunits: JSDK, comprised of Kim Jung-min, Simon Dominic, Lee Dong-hwi, and Lee Sang-yi, and M.O.M, which consists of Jee Seok-jin, KCM, Wonstein, and Parc Jae-jung. They made their official debut later that year with the covers "Journey to Atlantis," "Resignation," and "If," followed by the Number 1 hit single "Foolish Love," included in their first studio full-length MSG Wannabe Special Album. Also in 2021, their single "Only You" reached Number 2 on both the Gaon Singles Chart and the K-pop Hot 100. In 2022, MSG Wannabe returned with the non-album singles "I Love You" and "Do You Want to Hear."
