That day, Su Hui had requested a day off and specifically went to spend time with a college friend who had recently graduated from the police academy; the two met for afternoon tea at a restaurant.
Since it had been a long time, the two chatted on length. In their line of work, once the conversation turned to work-related matters, such as what cases they were currently handling, it was really hard to stop because there was just too much to talk about.
Her college friend mentioned a case she had just handled, where an elderly couple reported their son missing.

Because his parents disapproved, he had cut off all contact with them after joining the gang, which left his parents with no choice but to report him missing.
