We continue with Young-Min Jo's arrival at Min-Pharma world headquarters in Toronto.  Having avoided confrontation with security guards at the front gate, he is next to encounter his twin brother's head of security Xi Jiu Xiu, aka Zero.  Though forewarned they are identical and that the effects of time dilation will mean Kwang-Min's brother might in all likelihood look much younger and perhaps more appealing than the boss himself, Zero is nevertheless taken by surprise.  Not only that, she's instantly smitten.  For Young-Min it's the same.  

We then flash back to Zero's origins and the events which led to her eventually coming to work for Kwang-Min Jo.  The harsh existence she had to endure as a child, a teenager, and even a young woman, is described in graphic detail.
