He was once the favored heir of the Ye family, one of the capital's most powerful clans, but on the night the family fell, he was secretly sent away. He dropped out of school as a teenager to enlist, becoming an elite special forces soldier and making a name for himself through ruthless tactics on foreign battlefields. After retiring at twenty, he built a mysterious organization overseas and moved the world behind the scenes. Now he lies low in the misty city of the southwest, presenting himself as the owner of a "decent KTV." By day, he is a down-and-out second-generation rich kid whom everyone laughs at, drowning himself in drink and pleasure. In secret, however, he is the mastermind controlling an intelligence network in the shadows. Every inch of light and shade in his private rooms conceals a deadly plot.
