Lee Han-young - Ji Sung

Presiding Judge at Chungnam District Court

I am a criminal who squandered his life. This second chance is my period of probation.

Once an obscure judge, he sold himself to Haenal Law Firm as a son-in-law, then habitually conducted solicited trials. At first, it felt awkward. However, using a judge’s authority for private gain seemed to cause no issues. He soon grew accustomed to believing that the power of a judge was his personal right.

Lee Han Young turned out this way when he realized that not all judges are equal. Even in the court, prestigious university ties and successful parental backgrounds mattered. Han Young, however, graduated from a provincial university, and his parents ran a junkyard. That is why he chose to become the son-in-law and "servant judge" of the powerful Haenal Law Firm.

The prestige and promotions followed, but so did the whispers. He was no longer an arbiter of law. He was a corporate tool, and had to rule on cases handled by Haenal Law Firm exactly as they wished. Still, he thought it was worth it. By doing that, he could keep his mother comfortable and pay for his father’s 200-million-won-a-year dementia care.

But eventually, he found out his hands were empty. In his pursuit of having it all, he had discarded his true self. A sense of self-loathing washed over him. When his mother collapsed after becoming a sinner to her neighbors because of his corrupt ruling, he knew he couldn't go any further. Even without Prosecutor Kim Jin Ah screaming at him to "judge according to the law," it was time to stop. He had to live a proper life. He had to change.

However, redemption came at a price. The moment he dared to defy a verdict scripted by Haenal, he was framed and met a tragic death.

Who said life only happens once? At the moment he thought everything was over, Lee Han Young returned to 10 years ago, back to his days as a single judge. How did this happen? As he starts his life over, Han Young realizes: in this second chance, he must become a better person through new choices.

Kang Shin-jin - Park Hee-soon

Seoul Central District Court, Chief Justice of the Criminal Division

I decide what crime and punishment is in South Korea. The judicial branch is my authority.

He never trusts anyone. He believes only in others' weaknesses, and that is precisely what he considers strength. With sway over the illegal campaign funds of past and present presidents and the various corrupt practices of conglomerates, he wields immense influence over the judiciary branch through vast slush funds and judicial dealings. What’s more, Shin Jin knows the real weaknesses and greed of all the officials in the business and political spheres. As long as they cannot abandon their greed, the nation will remain in the palm of his hands.

Innocence and guilt are at his discretion, and this can bring any company crashing down. He uses the law and justice as a tool and is no stranger to judicial collusion. Not only the judiciary branch, but even serial killers are at his beck and call.

Anyone can criticize the rulings of the judiciary branch, but no one can change them. Therefore, Shin Jin views the judiciary branch as the ultimate powerhouse wielding the absolute weapon, the law. He intends to run the judiciary branch flawlessly and systematically after creating “judicial continuity”. And from his seat high up, he seeks to instill his own arrogant version of justice.

Kim Jin-ah - Won Jin-a

Seoul Central District Court, Prosecutor

As she studied diligently and her grades went up, her father suffered great hardship, breaking his arms and legs.

Jin Ah’s father was a hired thug who blackmailed people displaced by redevelopment for aggravated assault by threatening to harm himself. However, he was a good father who wished his precious daughter would be happier than anyone else. Her father, not wanting her to go down the path he did, gave his all in extorting others, while she poured herself into studying in hopes of getting away from him.

However, her father was the first to go. On the day she was accepted into Hankuk University’s law school, he collapsed while on a blackmailing operation. From that day forward, her father was bedridden, and the bonus he received from S Construction was used for her admission fees. Only then did she become honest with herself. All along, what she hated was not her father, but herself, the one who had grown up feeding on his pain.

After becoming a prosecutor, Jin Ah finds out the truth. Jang Tae Sik of S Construction was behind her father’s quadriplegia. From then on, she became a madwoman plotting to get Tae Sik back. Despite being called a rabid lunatic, she had her eyes set only on Tae Sik. But this proved to be too much for just one prosecutor. She could not just give up, and that’s when Judge Lee Han Young appeared. He stretched out a helping hand, saying he would help her catch Tae Sik. With only a moment’s conflict, Jin Ah takes him up on his offer. However, Han Young is fighting a great evil that Jin Ah never imagined.

Yoo Se-hee - Oh Se-young

The youngest daughter of the head of Haenal Law Firm

With looks that rival those of a celebrity, she’s a disrespectful snob who wouldn’t hesitate to put her hands on someone either. Everyone in her family is either an attorney or a legal professional, except her. However, this has never once made her feel inferior. All men bow before her eye-catching, superior looks and her status as the youngest daughter of a prominent law firm owner. Even the so-called “viper” of the firm, Yoo Seon Chul, was no match for her. Se Hee looks pitifully on her older brother and sister who only studied, did as their father said, and were never really able to have fun. It’s not like getting a license to practice law will make you the heir to Haenal Law Firm anyway. Based on what her father does, the owner of Haenal Law Firm manages lawyers and clients well.

In a past life, she lazed around in the office until she was over forty, bossing around her judge husband Lee Han Young like a servant. After all, the only person in the household lower than her was Han Young, who had come in as a servant son-in-law. But strangely enough, in this life, Se Hee is drawn to him, and for the first time in her life, she loses her wits in front of a man.

Jang Tae-sik - Kim Pub-lae

CEO of S Shopping

A person tightly bound together by nothing but greed and selfishness. Even murder is not off the table if it’s for his goals. Tae Sik has joined forces with Shin Jin, so he fears neither the law nor tax evasion. Even if you evade hundreds of billions in corporate taxes, Shin Jin will bail you out up to 50 billion. Come to think of it, the law is a cheap bargain for those who have it in their grasp.
