The other B2ST members were nowhere to be found when rapper Yong Jun Hyung joined Eru on stage for the balladeer’s August 9 comeback performance on Mnet’s M Countdown.

Eru recently made his comeback with single Hate You, and the B2ST rapper not only lent a verse to the song but appeared in the music video as well.

Yong Jun Hyung was seen with his hair slicked back and dressed neatly in a white button-up and gray vest for the performance, while Eru looked sharp in a white suit.
