During the Republic of China, the Han family faced collapse because a traitor leaked company secrets. Han's father sent his only child, 19-year-old Han Geng, to Feilengcui to avoid the disaster. Therefore, Han Geng had to separate from his teacher, Jo Kyu Hyun, and their romance was hindered. Han Geng sang in a Chinese bar in Feilengcui and met Jin Heechul, the leader of the illegal organization Tuberose, and the two became brothers. Cao Guixian, who stayed in Shanghai, almost became the illegitimate son of Mr. Zhao to replace the eldest son of Zhao who was killed by a car. He woke up and started the business of secretly selling arms. Fortunately, he was rescued by his friend Yu'er. Qi Liangren, an undercover lurking in the Zhao family in Yu'er's organization and Han Geng's good brother, was hanged because his identity was exposed. More than ten brothers who were traveling with Yu'er all died in the process of rescuing Cao Guixian. A few months later, Cao Guixian saved enough money to go to Feilengcui to find Han Geng. The two spent a dangerous time, but everything was solved with their mutual love and concerted efforts. No one knew that all this was actually just a conspiracy by Mr. Zhao, either to get revenge or to get Han Qiu, the uncle who loved Han Geng the most. But in the end, he realized that this was just a misunderstanding. He had misunderstood Han Qiu's intentions, and regretted it.
