I have one major problem with this drama and that's the pacing/flow. Stories don't progress in parallel, the writer dedicate a chunk of episodes for every side story while making almost no progress on the main story. For example, Nam Seon story took a big chunk and it was the main focus during that to the point everything else was put on hold. Even the leads weren't safe from this practice. After the first 30-40 episodes they almost had no role in the story. Another thing I didn't like is how inappropriate some characters' inclusion in the story. For example, Noh Young Ki had absolutely no business in shoving in himself with the leads. Completely out of place and was only done because the writer didn't write anything else for him. There were a lot of trashy characters in the drama and the writer's solution to fix them is to take away their money. Basically, the writer is telling us that rich = trashy.
