My main complaint with the show is that it reached its logical conclusion in episode 12. This is when ML and FL were already a couple and the mystery behind the kidnapping was resolved. The rest of the episodes were just filler without a plot. When there is no conflict and nothing to resolve, the story becomes stale. There wasn't even that much conflict with the older brother. He just kind of became irrelevant after the kidnapping mystery was resolved. The animosity between the brothers also looked forced because of the lack of plot development. When Young Joon told Mi So that his brother was a "bastard" and there were issues with their childhood friends, it implied that there might've been past bulling or some other conflict which had nothing to do with the kidnapping. But, it was just the kidnapping. To make matters worse, the issue between the brothers was forced on them by their parents who lied about the kidnapping for their own good, which was a pretty stupid plot device because it did not justify all the animosity. And, after it was resolved, everyone acted like nothing happened for the last 4 episodes, which was especially disappointing because the kidnapping and resulting trauma were an important plot point central to ML's and FL's character development and the writers made it completely superficial and unimportant at the end.

The resolution to the plotline of Mi So wanting to find herself felt like a cop out. At the beginning, she wanted to leave the company to find a husband. Then, that plotline was abandoned just to resurface at the end where Mi So realized she wanted to continue being Young Joon's secretary because she loved him. And, she remained his secretary after marrying him. This was rather a strange choice for a wife of a CEO to have the same position as his office employees, instead of holding a higher position for which she was actually qualified.

One of the things I liked was that FL had enough sense to pick up on the nuisances about ML's behavior to discern that there was a lot more to the kidnapping story than what she was told. I loved that she did not just blindly believe everything she was told and started having a crush on the older brother, which would've resulted in a very stupid love triangle. She suspected from the very beginning that Young Joon was the one who was kidnapped, which led her to the truth. In return, Young Joon transformed from a self-centered person to a thoughtful and caring boyfriend and employer. The main couple also had very nice chemistry and some very steamy scenes.

Other than that, there wasn't much else going on. The side characters were not interesting enough to carry the plot. I ended up skipping most of scenes in episodes 13-16 and just watched the ones with the main couple to get to the end faster.
