On the June 1 episode of the Mnet music variety show, Pentagon's Hui took to the stage once again as a singer-songwriter! For this semi-final round, Hui composed and wrote the lyrics for his song "Swim Good", a steamy trap song featuring KARD's Somin. On the live stage, Hui and Somin swept the venue as they sang and danced like a perfect duo!

What do you think of the two idols' performance? The next episode will be the show's final round, so make sure to tune in on June 8 at 9:40 PM KST!
