The boys of Supernova recently made their comeback to the K-Pop industry, as they released their MV for the title track, On Days That I Missed You, as well as their mini-album, Time to Shine. Soon after the release, the boys performed their first comeback stage on yesterday's episode of Mnet's M! Countdown, and Supernova's next stop was KBS Music Bank this evening! After being away from the K-Pop industry for quite a while, the boys are back looking even better than ever, as their performance of On Days That I Missed You today was terrific! Check out their comeback performance below.
