After School's Jooyeon tweeted a set of photos from the set of her current drama, KBS's 'Jeon Woo Chi'.

"Can't live without hot packs??" she posted, apparently having a tough time in the freezing cold for outdoor filming. "Hardworking in the cold, Jeon Woo Chi team fighting^^?"

Jooyeon is playing the role of Eun Woo, a female warrior and royal guard, alongside fellow After School member UEE, who is one of the main characters in the drama.
