Woo Young Woo’s father was concerned when she was a child because she didn’t utter a word until she was five. Her father had no idea how to raise her with autism after the doctor diagnosed her. When they returned from the hospital, the landlord began to yell at him. A misunderstanding occurred. Because he believed his wife was having an affair with him, the landlord started beating him. Young Woo made her first word at this point. She detailed the laws prohibiting physical abuse in her statement. Young Woo’s father jumped with joy as it ended their argument.
When Young Woo’s father questioned her if she had picked up the phrase from a movie, she pointed to the tall stack of legal books. She had read the entire book of laws when she was five years old, and Young Woo’s father was a lawyer. Young Woo did end up becoming a lawyer, just like her father, as the landlord’s wife had predicted. Young Woo joins Hanabadara Law Firm, one of the best in the nation, after graduating from law school at the top of her class. Her father advises her not to do unnecessary things on her first day, such as her humorous introduction, talking about whales, and paraphrasing other people’s sentences.
Young Woo lives with her father and is socially adept and independent enough to travel alone. Her father has taught her how to comprehend emotions and respond appropriately in various social contexts. She has trouble getting through a rotating door on her first day at work, but Lee Jun Ho, who she meets, helps her. At the Hanabadara law firm, Jun Ho, a senior attorney, directs Young Woo to meet her mentor, Jung Myung Seok. When Young Woo introduces herself to her mentor using the humorous opening line her father had warned her not to use, he expresses scepticism toward her. There is a special note from the CEO of Hanabadara on her resume to take special care.
After speaking with the CEO, Jung Myung Seok gives Young Woo a straightforward case to practice on. His subdural hematoma was caused by a woman hitting her husband. The woman is charged with trying to kill someone. Young Woo discovers that the elderly woman she meets is the same one who advised her to pursue a career in law. His wife hit him with iron while arguing because her husband was easily angered. The husband wants his wife to take care of him as compensation but does not want to go to court.
Young Woo observes, however, that the elderly woman is financially reliant on her husband and will not be able to inherit anything from him due to the attempted murder charge. Young Woo makes Myung Seok take notice, and she is permitted to present the case to the jury court.
When the husband realises Young Woo is the daughter of the man who had an affair with his wife, he begins cursing at her. Young Woo believes that the woman should be accused of causing physical harm rather than attempted murder and that her husband’s bad behaviour is the ideal justification. The husband is brought into the court by Young Woo, but before she has a chance to question him, he starts berating her and attacking her. Young Woo informs the judge that the man has a bad temper and that the woman has cared for him for a long time despite living with him. Young Woo requests that her crime be changed from attempted murder to physical injury, but they learn that the man has been dead.
Because the man passed away shortly after their argument, Young Woo feels responsible for his death. Now, she must work harder to avoid accusing the woman of murder. She keeps reading the statement until she discovers a significant hint. The elderly man claimed in his statement that he had suffered from a severe headache for several days before the incident. In the courtroom, Young Woo questions the doctor about the possibility of fainting from an existing hematoma. The physician acknowledges that it’s possible. Young Woo’s company also provides a report from other medical professionals, enabling the woman to be charged only with physical harm and not murder. Young Woo shows everyone that she can be a lawyer despite being unique.
