I don't know why but when I had initially tried watching this show, I couldn't. When I tried the second time, I realized that with each episode I wanted to know more about the story of SWJ and HDJ. The story for me felt like a warm yet nostalgic cuppa. It's a melodrama so expecting to instantly like or get hooked on the 1st episode is not a good idea. I liked the development of the main characters. They were both flawed yet at the core, both of them were good, I think DongJin and Woojoo were the best for each other because he was initially a pushover and needed someone to not pity him but show him what he was doing not entirely right, and someone needed to make Woojoo realize that taking revenge wouldn't make everything go back to normal. I would, however, want the reunion to be a bit longer, but it aligned well with the rest of the episode. The filter, the back and forth of the times, and the prologues at the beginning of some episodes made the show interesting. However, it would have been better if it was 12 episodes rather than 16. But I would say this is worth watching because you will see how a broken girl could be strong enough to protect the right people.
