Yoo Seung Ho and Park Min Young will respectively be playing Seo Jin Woo, a genius attorney suffering from excessive memory (possibly hyperthymesia), and Lee In Ah, who transforms into a mature lawyer. Yoo Seung Ho's character engages in a fight in order to prove his father's innocence in a murder case. Park Min Young's character will be as cute, bright, and clumsy at first, but she will change as she watches Yoo Seung Ho, whom she's known since childhood, struggle in order to fight against injustice.
In related news, actor Nam Goong Min is in positive talks to appear in the drama, as well, but not confirmed as of yet.
Logos Film insisted that the drama will not be focused on being a legal drama, but rather focus on being a legal human drama, meaning they hope to focus on the compassionate aspects of the story, as well.
