In the beginning "A Man in a Veil" has an interesting story line, however, it gets flat after a mentally challenged character Lee Tae Pung becomes Yoo Min Hyeok, a lawyer with a Savant Syndrome condition. Actor Kang Eun Tak does well portraying a mentally challenged Lee Tae Pung, however, the lead characters Yoo Min Hyeok and his love interest Han Yoo Jung cannot develop lovable on-screen chemistry. They look like a puppet and a beautiful doll when they are on-screen together. Also lawyer Yoo Min Hyeok loses his focus and he lets Han Yoo Ra character portrayed by Actress Lee Chae Young takes over with her tantrum. Actress Lee Chae Young has all the facial features of an evil Han Yoo Ra, also her facial expressions tell the story of her evil intentions. Actor Lee Shi Kang steals the show as a spoil rich son and also as a lovable Director Cha Seo Joon that is able to convey his fondness and love to Han Yoo Jung.

The story gets interesting again after the Chairman Cha Woo Seok meets his former fiancee Yoon Su Hee / Seo Ji Sook. These two veteran supporting characters help catalyzing the events and make the story growing in intensity again. The two young supporting couples Kang Ye Jin and Han Yoo Myung portrayed by Chae Bin and Jang Tae Hoon are memorable; they are able to develop good on-screen chemistry that the leading characters fail to achieve. The appearances of supporting characters, Chairman Cha Woo Seok & Yoon Su Hee/Seo Ji Sook and also Kang Ye jin & Han Yoo Myung are appealing.
