I liked the concept, but overall, it was mediocre. I never understood why the killer was going after them. There was also too much back and forth. Even when the killer died at the end, she kept her distance for no reason until the main character told her that he remembered everything.
I just finished this. I'm not usually a fan of dramas, but this one truly touched my heart. It's probably my favorite drama series I've ever watched—it moved me deeply.
