This show is totally different from the other dramas, it's a really sad drama but the way they made the show, including plot, couple dynamics and characters is very interesting. Starting by the plot, is something I've never seen before for a k-drama, and considering the other dramas I've watched, this one had the best rollout for a couple who have met when they were kids/teenagers, like it had a purpose and consequences in the drama. What I liked the most about the show was the main couple dynamics, the female lead was actually the one pushing for the relationship and she wasn't afraid to show she was interested on the male lead, but also he always cared for her and he was actually the one to be more affectionate when they started dating. The only thing I have to complain about the show is how they handled the last episodes, they didn't show how the memorial which the main characters were working on during the whole show turned out and they came with a whole disease for the male lead that it felt like an excuse for him to get back with Moon Soo. It's still one of my favorite dramas because the story was great and the couple had a great chemistry
