Afraid that she might accidentally lose the button, she strung it through a red thread and wore it as a pendant of sorts around her neck.
Five days after the incident, there had been an anonymous tip to the police station reporting that the mastermind behind the abduction was someone by the name of 'Brother Kun'.
With that lead, the police had interrogated the young man and fatty, and they'd managed to pry from their lips the full name of Brother Kun; it was Xie Kun. Most likely, he had gotten wind of the plan's failure because when the police raided his lair, the man was gone.
Regarding why they were targeting Song Qingchun's life, the young man had said Brother Kun had promised them a large sum of money after the deal was done to help them escape the country. Xie Kun didn't give them the exact reason, so the whole truth could only be exposed after Xie Kun was behind bars.
