A senior associate lawyer in his ninth year, An Ju Hyeong seems cold-blooded, but no one can deny his competence in the field. He became a lawyer simply because he found logic and cases interesting, but from the start of his career, he never grasped the idea that lawyers are supposed to protect the weak, uphold justice, and make a difference in the world. Although he's a veteran among associates and has even set a new salary record, he refuses to open his own practice, finding it too troublesome. But now, the once-peaceful walls of his workplace are beginning to crack.
