They have been known as brother and sister since childhood in the "Six Sons' Brothers". She relies on him and acts coquettishly towards him, while he protects and dotes on her, but keeps his love deep in his heart. She is the soul of international piano poetry, and he is the "Iron King of Hell" in the legal world. With the help of fate, the two of them went from being "brothers and sisters" to being "married in life and death." They experienced misunderstandings, cold wars, and seas of jealousy. Finally, under the witness of love and time, they broke through their guard and finally got married.
