JUNHEE, the leader of the K-pop boy group A.C.E., is going solo this year! The lead vocalist of the group made a stunning solo debut on August 14, 2025, with the pre-release single “Supernova” from his upcoming (and yet untitled) solo debut album.

“Supernova” is a song sung entirely in English. The music video begins with JUNHEE in a club, as he is offered a mysterious green drink. As soon as he drinks it, music pulses through his veins, and he croons to a pop romantic number. He refers to his and his lover’s love as a supernova. The song is groovy and fantastic with its pop and dance tunes, which are complemented with his smooth delivery of choreography. The confluence of R&B and pop genres presents an electrifying experience.
