During the August 26 press conference for 'Our Gab Soon,' reporters asked Kim So Eun whether she's got any advice for co-star Song Jae Rim, who's never worked on a drama that is 50 episodes long.�

After some thought, Kim So Eun replied, "A 50-episode long drama is not easy for an actor. You not only have to take care of your stamina and health but you also have to maintain the [on-screen] chemistry to make sure its consistent. Song Jae Rim takes good care of himself on his own. So I don't really worry, and I don't think I need to give him any particular advice."
