A couple of days ago, it was reported that f(x)'s Luna was cast for her first acting role alongside SS501's Kim Kyu Jong for TV Chosun's new weekend drama, 'Saving Ajumma Go Bong Shil'. New pictures of her from the set of her first filming were released today, showing the rookie actress hard at work. Despite it being her first time acting on a set and not a stage, fellow co-stars were impressed with the level of professionalism she showed. One of the scenes required her to doze off in an intoxicated state, which Luna pulled off without a hitch. On breaks, she acted as a breath of fresh air for the tired staff, regarding everyone with a bright, positive smile. Luna will be playing the role of the maknae daughter 'Seo In Young' in the drama.
