Liu Ya Jin

She (played by Lu Zi) is a top bodyguard in the security industry, while he is a key decoder who holds the key to a crucial password. To protect him and an encrypted disk that can expose the shady technological secrets, she engages in a life-and-death chase with various hunters. When her relatives betray her and trust collapses, she must choose between professional rules and justice in her heart—should she fight her way out for him or fight alone for the truth?
