Upcoming drama Master's Sun has cast INFINITE's L to play the young version of So Ji Sub's character Joo Joong Won. We all know L from his starring role in the K-drama Shut Up Flower Boy Band as Lee Hyun Soo. Originally, the role was going to go to another K-pop Idol, Hyungsik from the group ZE:A, but things fell through for him and now he's supposedly confirmed for a role in The Heirs, also starring Lee Min Ho. During the recent press conference for the drama, So Ji Sub commented on the use of Idols in dramas. He said he didn't see a problem with it, and when they're on set they are there as actors and not Idols and work hard. L's role as the young Joo Joong Won will show how the character grew to become a heartless and stingy person. He'll also appear in the flashbacks the older version of his character will have. Master's Sun is set to air after the conclusion of I Hear Your Voice. KrisE! @K_Kisses_KrisE (Source via yahoophilippines and
