It is true that the show had many flaws, but I would say it is worth watching. Yes, they had a strong build up for the second couple, but we are left unsatisfied as we are unsure if they end up together. As for the main couple, the kiss scenes were indeed lacking passion. However, since the story builds into this stressful scenario where all the worst things that could happen do, seeing the efforts of Ji Won Young to attempt to save the relationship was very touching. Even though there aren't a lot of romantic scenes, it does make me admire the small things they do for each other, and the hugs that Yoon gives to Ji was the most comforting and warm-hearting scenes that I have seen.
