Only two weeks until the premiere of Ji Chang WookYoona, and Song Yoon Ah's new action melodrama The K2, and in the latest teasers from tvN, we are introduced to the three main characters' conflicted personalities and motivations.

In The K2, Kim Je Ha (Ji Chang Wook) is a former secret service agent, unquestionably patriotic yet abandoned by his colleagues. An elite soldier, Kim Je Ha is also tremendously athletic, armed with martial arts skills and ice-cool nerves known to few. He gets hired as a bodyguard by Choi Yoo Jin (Song Yoon Ah), the premier First Lady candidate and the daughter of a chaebol family. Behind Choi Yoo Jin’s kind and friendly demeanor, though, lies a woman with deep ambition and a ruthless willingness to pursue it at all costs. Amidst his struggles and her ambitions, there is also Go An Na (Yoona), the reclusive and hidden daughter of the presidential hopeful, who, due to a childhood trauma, is unable to communicate with the world and only sees love as a tool for revenge. So when she and Kim Je Ha, both abandoned souls slowly growing closer, decide to enact vengeance upon the people who wronged them, can they put their own traumas aside and focus, or will their emotional scars cause them to fail in their quest for retribution?
