This was Yoon Se In's first drama out of 3 and it seems she quit acting I wonder why? Anyway, the 20 episodes had a good build up and put the story in a good place but unfortunately it tumbled on itself and didn't get anywhere. The story fell flat and none of the bigger events had much weight. The story changes randomly to suit the writer without meaningful justification/resolution and some are just cut off without a mention. Like the breakups/reconciliations happening or that raging son or the orphan one.
