Qiao Yuning returned home and went straight to the Zhou Group, where she reunited with her mortal enemy Zhou Shixu. The two were childhood sweethearts, but they were often at odds with each other - she blamed him for breaking the appointment in London, and he was angry with her for blocking him, and they were full of care during their quarrels. From the misunderstanding of Yu Yaxuan, spending 1 billion at the auction to win her favor, to living together to take care of each other, and working together to deal with troubles, Huanxi's enemies gradually grow in love while fighting each other. Zhou Shixu went from being hard-spoken and soft-hearted to pursuing love outright, and Qiao Yuning also went from being tempted to being tempted. In the end, amid the fireworks at the birthday party and the drone proposal, the "out of control" rivals finally became each other's destination for the rest of their lives.
