Lin Nian, a bank manager who had been soft-spoken for five years, learned to be ruthless the night his boyfriend and his best friend teamed up to frame him for taking bribes and suspended him from his job. She doesn't understand crying, she only understands reports, regulations and people's hearts. When she returned to the workplace with evidence and transformed from a marginalized person into a precise hunter, she met Gu Zhun, the branch's new general manager of risk control - the cold-hearted boss who only insisted on "procedural justice" when she was in the most embarrassing situation. The two went from testing and gaming to working side by side. She made her opponent overdue for greed, while he guarded the rules and protected her who was almost swallowed up in the financial street. This is not redemption, it is two people who respect the bottom line and finally stand on the same line of defense.
