It's been a while since we heard about Supernova (aka Choshinsung) in Korea. Having collaborated with T-ara for TTL and TTL Listen 2 in Korea last year, the boys have been busy with promotions in Japan since.� However, they will be making a comeback in Korea this August! Ahead of their scheduled comeback on August 19th on M! Countdown, they have today released their MV teaser for their comeback title track, On Days That I Missed You (?????). Many thanks to kyulee for the tip.
