Recap: 5 years ago, both Han Chen and Su Mian mysteriously loses their memories. 5 years later, they meet again. Like 5 years earlier, the Alphabet Syndicate comes into their life, trying to separate them as their leader, S, is infatuated with Su Mian as his brief encounter with Su Mian in a cemetery slowly becomes an obsession. His jealously reaches a peak when he realizes that it would be impossible for him to be with Su Mian, not just because his father was her father’s killer but also because she has now fallen in love with Han Chen. Desperate to obtain her, he comes up with a plan that successfully separates Han Chen and Su Mian for 5 years and allowing him to become Su Mian’s closest friend at the cost of breaking apart the killer syndicate he created himself and giving up on the crime empire his father had built for him.
