I personally liked it. I have only read chap.1 of the webtoon (b/c I am not someone who reads webtoons) before I started watching this drama, so I can't compare the two. But I thought the drama was made really well and the entire cast did a stellar job. Story: About a man called Frost who due to an accident when young lost most of his emotions and had his hair turned white. He and his team of "buddies" solve cases dealing with psychology. Every episode deals with a different case - but there is one underlying case involving Frost that starts showing itself mid-way. Cast: Dr.Frost (Song Chang Eui) This is the first drama I am recognizing him in and I think he did a great job, he's attractive even with the 'white' hair ;) His very rational and thought processing mind was very believable. I liked how I could see the puzzle pieces come together in his eyes. I wouldn't mind working for him myself^^. Yoon Seung Ah (Jung Eun Chae) First time I've seen this actress too, I liked her as the novice apprentice who has a totally different character than Frost - they worked well together. Cheon Sang Won (Choi Jung Woo) was great as the head professor. (I always enjoy seeing this actor in dramas). Song Sun (Lee Yoon Ji) at first I didn't like her b/c of her animosity towards Frost but about half-way in the drama, she stopped acting rude and was then pleasant to watch ;) Nam Tae Bong (Sung Ji Ru) I loved him as the Detective - always bringing new cases for Frost to help solve, he made the drama even better by being there. All the supporting and guest characters did a good job. Music: It was good and suspenseful at times but I don't remember any actual songs. Re-watch Value: 5.5 - If I get hungry for some psychological stuff again I may re-watch a couple episodes here and there.
