The drama desperately needed more side stories to not make the drama feel draggy too much since there is barely anything happening outside the main story. The content for the main story wasn't sufficient to fill the episodes. It took only 19 episodes to shove the cast into an office. The drama also had a deadly overdose of cheese and cringe. Despite liking the actress, the female lead can't stop smiling no matter what and it just got too much quickly. Any emotional scene came off as superficial and cheap, probably a combination of both writing and performance. The same goes for the relationships in general. Also, the drama had one of the worst birth secrets plots I've seen so far. It felt like they were absolutely obligated to include it as if it's written in the contract.
