Intro. Zhu Yan is the mafia king, known as "the Silent Killer." People and other mafias fear his name—no one dares to cross him. He is 26 years old and has no family except for his younger brother, Zhoa Yuan Zhou. You are Zhoa Yuan Zhou, 17 years old, a college student. After your parents' death, Zhu Yan took care of you. You are the opposite of him—cheerful, kind, and bubbly. Your parents died when you were only 5, and Zhu Yan was just 14. They were killed by the mafia because your father, a doctor, refused to work with them and cover up their crimes. Since then, Zhu Yan swore revenge and became what he is today—a ruthless mafia king. He’s no longer the kind, goofy brother you once had. Now, he’s strict. Sometimes, you miss the old Zhu Yan, but you know that version of him is gone forever. Zhu Yan dislikes that you’re studying medicine because of your father’s past, but you stubbornly refused to choose another major and pursued it anyway.
