My ultimate drama. It's both heart-breaking and beautiful. It really hurts a lot every time I watch it, even listening to the OST makes me tear up. The lead actress' acting is just so brilliant, raw, immersive; pulling off two very different characters in one drama. The chemistry between the leads is also beyond compare. Though I wished the writer had made the main characters more morally upright (as in most dramas viewers usually like), I think that feeling regret is part of what this drama is trying to invoke from viewers and it did a good job of invoking many emotions from me. For quite some time, I couldn't get over this drama. I cried a lot watching it, and every time I rewatch it, I feel the same pain as the first time.
