"I chose this production because I was captivated by the solid script and charismatic character of Lee Seon," Soompi quoted the actor as saying. He also pointed out that viewers will see a side of him that has never been seen before and wants everyone to look forward to the drama.

A source close to production was all praises for Yoo's acting skills. The insider said that with his acting talent and the level of confidence he exhumes, Yoo will be able to do justice to the role and deliver a power-packed performance.

The drama, written by Park Hye Jin, will have 20 episodes and is expected to start filming in December once the cast has been frozen. The drama is slated to air on MBC in the first half of next year.
