This drama is not for everyone. It won't sounds good but it's for those people who understands deep thoughts, meaning of hidden concept or whatever. This drama shows how you will connect with different people who aren't normal or have different characteristics. But I'd highly recommend to watch and I'm sure it's worthy to watch. As a Kim Soo Hyun fan you have to watch this and Seo Ye Ji also nailed it in this drama. It's a great comeback for Kim Soo Hyun. If you're fickle minded then it may feel boring to you. But it won't be waste I hope so.
