Yesterday, we reported that 2PM's Junsu would be guest-featuring on Kan Mi Youn's latest single, 'Sunshine'. Though the single is scheduled to hit stores on February 17th, the full music video has been released today. 'Sunshine' is a special re-arrangement of a track that Junsu composed four years ago; he gave Kang Mi Youn the track as a gift in support of her comeback. Check out their duet studio MV below.
