Large age difference between Chang wook and Choi Sung-eun is way too large (9 years). It is weird IMHO. The plot is strange and doesn't make sense. Even though I didn't like this drama, seeing the great actors Kim Hye-eun and Yoo Jae Myung working together is extremely special.

I was impressed by the acting of Hwang In Yeop because his role is arguably the most challenging to pull off. Ji Hye Won was also impressive. She convincingly played a protagonist role. I look forward to watching their work in future.

Chang wook's performance wasnt compelling. He plays himself again rather than the character. I loved his work in Healer and K2 but since then his performances haven't been noteworthy. He should stick to action and musicals.
