It stars Rui En, Chen Liping, Rebecca Lim, Tay Ping Hui & Elvin Ng as the casts for the second series.
In reality he is a serial killer targeting people who abused their family and children, and chose to woo Xiaoman because her father was a pedophile who sexually assaulted his childhood friend Thomas (Who died back in Season 1).
He had actually been practicing to walk for months, and tried to protect Lelin by making a false confession that he murdered Rookie and Monkey for raping his sister.
The fourth target was initially believed to be her own husband, but was revealed to be Yang Qiujun, mother of Hu Xiaoman, the lawyer who defended her.
Yao Wanyi never made it to her fourth victim (Jieyu did it instead), and was accidentally run over by a car on the final episode as she tried to flee from Xiaoman and Da Bao.
In a past case, it was revealed that Xiaoman believed that Fang Rongge was the mastermind behind a serial killer who went about cutting off people's vital parts (Which is now emulated by Yao Wanyi).
He allegedly committed suicide by blowing up his own car while he was still inside, which devastated Jieyu and turning her onto the path of a vengeful serial killer.
