I loved the beginning. Especially the way Sung Deok-mi's job as a curator was presented. The characters and the way how the main leads came closer were also well written. But at some point the storyline lost its charm and all the casual plots were told about the coincidence finding a lost child and how the main leads realized they knew each other since childhood. It's nothing new and it's predicable. Because of this, the series was not emotionally touching. I stopped watching it at episode 12 and needed to motivate me to finish it. Nevertheless, I loved the way how healthy their relationship was and how kind they treated each other. It is a good counterbalance towards the toxic way of romance some series are presenting.
