Big Bang's Daesung will finally make his small screen debut on March 21st through the musical drama, "What's Up"! On February 15th, producers of the show revealed that the series will be airing after SBS's "Paradise Ranch" in the 9:00 PM KST time slot. The drama is based on the true story of a musical class at the Chungkang College of Cultural Industries and aims to feature the dreams, passions, and love stories of the young musical majors.  The drama has already received widespread attention because it's both Daesung's small screen debut, and is the work of writer Song Jina. Daesung will be seen with his castmates Im Ju Hwan, Im Ju Eun, Jang Hee Jin, Lee Soo Hyuk and many other young rookie actors. Since they're playing the role of 20-something theatre aspirants, each cast member received strict vocal and dance training for six months in preparation for their respective roles. Currently, the drama has completed about 90% of its total filming after beginning last July. Source: Sports World via Nate
