Kim Yong needed the perfect excuse to give up on his love. This is where Kim Mu-nee comes in. Even without Mu-nee's interventions, they would've broken up one way or the other. Mu-nee's role in the drama had a huge impact on me. Her character development was amazing. From the heartbreaking story in Kim Yong, she manages to perfectly dodge making the same mistake Kim Yong made. He lacked bravery. And from his lack of bravery, brought her courage. Very good watch! Wouldve liked to see how Mu-nee's parents ended up together tho
