I know a lot of people did not like the ending, but although it bothered me, it didn't ruin the drama for me. If anything, I just thought of it as a kind of messed up ending for a kind of messed up story. This kdrama felt so unique compared to all the other ones I've watched. The show showed all of the different sides of the story and how the plot points affected everyone. Like many watchers, the real stars of the show were In Ho and In Ha. Their storylines of broken friendships and what was lost brought so much emotion where I almost burst into tears for them. I never knew who to feel bad for in this show, which was really frustrating, but also shows you how good it is. The ending for the main couple was kind of eh (I hate it when the couple breaks up but comes back together because how unrealistic is it that they have spent all those years just waiting for each other! Also, In Ho cut ties with Seol and her family which was so sad because it was so heartwarming when they accepted him as almost family! And I wish the ending was more like Seol helped Jung change rather than Jung changed by himself away from Seol. Except I liked how the In Ho and In Ha sibling bond was saved.)
