You can enjoy this drama to the fullest because there are great actors and the story never get boring. In every episode there a "case" that the protagonists must solve meanwhile their own personal stories unfold and with every episode you can't wait to know more and more. The female lead is strong, gorgeous and vengeful and you can't help but fall in love with the seriousness she does her work. Also you will watch every episode drooling to know about her past. But beware! You will need a lot of tissues for every single episode. Prepare to cry because the main theme this drama talk about is suicide and how to prevent them. Also Rowoon and Lee Soo Hyuk are a pleasure for the eyes.
