The third episode of 'The King, Two Hearts' that aired on the 28th gave audience a fright. On this episode, Lee Jae Ha (played by Lee Seung Gi) and Kim Hang Ah (played by Ha Ji Won) get into a fight for their pride. They make a bet: the one who can run on the treadmill the longest wins. Hang Ah stated, "We're going to keep running. The loser has to leave."
However, the two realize that there's a bomb strapped on the running machines and will go off if the weight changes or if the machine stops. Lee Gang Suk (played by Jung Man Sik) stated, "We have to freeze the bomb before taking it off. It's going to take a few hours but it will work."
As times goes, the two start to get tired. The others at the gym are with them cheering them on. Jae Ha and Hang Ah also give support to each other.
Fortunately, they are successful in freezing the bomb and taking it off. Viewers can see that the experience made the two main characters grow closer together.
