I love this drama but I found the finale bitter because it's depressing. First, they didn't use the black box chip as an evidence because Tae Wook is afraid of what people will think about her wife although it will save her. Second, what happened to Prosecutor Byun and his wife, we all know that Prosecutor Byun's wife asked for Go Hye Ran's help for her husband. Third, what happened to their fight against Kang Yool? Lastly, why the police detective is dumb? Although his gut feelings are right that it is a murder he is just suspecting anybody.
I love the hidden signs, sweetness of Hye Ran and Tae Wook, the outfits of Go Hye Ran, and the soundtracks because it perfectly fits the show itself. But I hope that finale is a little bit Happy not Misty.
