In order to investigate the relationship between Qin Fei, the president of Nebula Media, and the death of his companions and biological father, Shen Yun went to Nebula for an interview and encountered an unexpected incident. Shen Yun was bravely injured and got a blessing in disguise. She successfully entered Nebula and met Shi Chengming, the vice president who wanted to drive Qin Fei out of Nebula Media. The two hit it off and cooperated to investigate Qin Fei. While the two were cooperating and taking advantage of each other, they also had a secret love for each other. As the second son of the chairman of Nebula Group, Shi Chengming wanted to be recognized by his father. Knowing Qin Fei's character well, he could not prevent his sister from marrying Qin Fei, so he tried every means to expose Qin Fei's true face and protect the family property. During the investigation, the two not only discovered that Qin Fei was stealing Nebula assets, but also found out that the Qin family father and son had fabricated evidence to cover up their crimes. However, the mantis stalks the cicada and the oriole is behind. Qin Fei had long known that Shen Yun and others were investigating him, and after waiting for them to find the evidence, he not only stole the evidence, but also killed Shen Yun's companion Gu Kai. In order to prevent Shi Chengming from being too involved, Shen Yun decided to marry Qin Fei's younger brother Qin Fan to search for evidence again. In order to protect Shen Yun, Shi Chengming deliberately framed Shen Yun for being arrested. Shi Chengming used himself as bait, and with the joint efforts of everyone, the crimes committed by Qin and his son ten years ago were finally exposed. In the end, Qin Fei, whose reputation was ruined, was desperate and planned to die together with Shi Chengming.
