I agree with the majority of comments on that this is just a bit of light viewing with no major tragedies or complicated…
I agree, but I think the show was trying to expose and diminish these societal norms instead of encouraging them. Correct me if I'm wrong but according to a lot of kdramas, these unfair and judgemental ways must be pretty common.
Many times I think Guwon doesn't care about his duty, all he cares about is Sarang. He doesn't care about employees…
He does do work according to later eps, and it was revealed that the other employees would also go on vacation taking turns. Sarang and her friends were just the first ones because they were the most hardworking (which is a fact from results).
