Li Ming Yang is an unassuming, and perfectly normal, office worker who was rushing at the end of the day to meet with his girlfriend for a date. Perfectly normally, he scans a QR code that he thinks is a promotional thing, but it turns out to be a far too mysterious, dangerous, and not at all promotional, thing.
