Cheng Ruoxun, a gentle girl from a girls' school in Suzhou, was selected by a Korean agent while accompanying her friends to a talent show and brought back to Seoul to work as a trainee at MS Entertainment Group. In the early days, she was shunned by other trainees because of the language barrier and because she was Chinese. Cheng Ruoxun gritted his teeth and persisted and got the support of Han Xizhu to start a career in the entertainment industry. He thought his career would be smooth sailing, but he was tricked by Kim Soo-yeon, who also became popular. First, he was late for the show, and then he was arranged to accompany the dinner. After Ruoxun narrowly escaped, he was set up to take over a script from a rival entertainment company. He was even framed as a drug-taking lesbian. His image plummeted, and the company decided to hide it. During this period, Ruoxun met Han Xizhu's brother Han Zhengxi, and with the help of Han Zhengxi, he reached the pinnacle of his career step by step, while Kim Soo-yeon eventually ruined her acting career because of her greed for profit.
