I personally really love mystery and crime dramas and this one is WORTH watching. Every mystery was solved so it leaves you with no questions and big misunderstandings. It's also really funny , which makes it enjoyable to watch. I especially loved the OST (that's actually what made me watch this drama). All of the main characters have a nice character development which is also really important. I even cried at the end even tho it was a happy ending. Anyways give it a try and I'm sure you won't regret it!!
