Very interesting plot and thrills along the way. They deliver the creeps and the justice nicely. And the bad guys you didn't have to wait til the end to be revealed. The ending was both expected and surprised me. I won't go into details but I'm glad to have watch it from episode 1 to 16 The drama to me is more on the bromance/brotherhood. The remember me/you part is not really for the romance arc, rather it's the mystery part. Its not a perfect thriller romantic drama because I did find myself skipping some parts. The acting is on par. I've always love J Na Ra. She's usually doing cutesy character so her character here as a detective is refreshing. And I have to say I love her hair here. So pretty. And as a detective she wears really sensible shoes (sneakers) unlike a previous HK drama where the detective wears fancy stiletto boots. And hello Chun Hee nice to see him on the small screen. I also enjoy Min character, he was both cute and creepy. What I did not enjoy. Sometimes the flow seems disjointed. Not sure if it was the editing or what. And I get they try to focus on the cases and the mystery of what happen 20 years ago so didn't have as much Ji An and Lee Hyun moments as I wanted. Lee Hyun character needs some warming up to. He starts off as a smart Aleck, know it all, rude and indifferent person. But as he Butts against Ji An and his story unfolds you do warm up to him. I also have to mention poor Ji An she's been attacked so many times I almost lost count. It's interesting to watch and find out the truth but not typical enjoyment cause it's slightly dark. I won't be rewatchin for sure
