The drama is a suspenseful love drama, which revolves around the hidden secrets of the chaebol family and the owner risk management. It tells the story of the chaebol heiress who lost her mother in a murder case 15 years ago and a third-rate lawyer who met to find the truth of the incident. It is worth mentioning that this drama is the first TV drama to truly describe the top team of owner risk management. Lim Soo-hyang plays Mok Seok-hee, the only daughter of the MC Group, who has both intelligence, appearance and financial resources. Although she appears to be a chaebol girl who ignores others, she is actually a person who is working hard to find out the cause of her mother's death 15 years ago. Lee Jang-woo plays Heo Yoon-do, who is more tenacious than weeds. Although he has nothing, he is full of love in his heart. He is a lonely third-rate lawyer.

He solves all kinds of troubles of community residents in a small room, and is miraculously poached by the MC Group's top team to become a group lawyer, where he meets Mok Seok-hee. Bae Jong-ok plays Han Teok, the "leader" of the TOP team that closely manages the "owner risk" of the financial world's first MC Group. As a consulting lawyer for the MC Group, he is known for his loyalty and devotion. He is also an omnipotent "secret power figure" who knows all the secrets. He is also an "ace figure". Whenever the boss's family gets into trouble, he will be active in all aspects to minimize the risks.
