William was selling his body to survive when a mob boss named Eric takes him in as his new lover. Even after being entangled with the dangerous mob, William found peace and fulfilment in his every day life. That is, until an accident takes Eric from him. Without Eric around anymore, William escapes the mob. As William lives a quiet life alone, a mysterious man from his past emerges, calling himself Nine, and William instantly recognizes him as Eric's adopted son.

With the boss dead, Nine claims that he had no place to go. The mysterious man has an air of danger about him, but on the flip side, he appears timid and unreliable. Unable to abandon the poor boy now with no one to turn to, William opens his home to the younger man.

Meanwhile, the mob is still digging into the truth of their boss's death. Was it really an accident? Or...was it cold-blooded murder?
