Loyalties will be tested. Hearts will be broken. Desire will be their downfall.

Middlesbrough's underworld is a dangerous game, and Matthew Smith finds himself right in the middle of it. A once-feared gang leader, he is now forced to be a pawn in a deadly cat-and-mouse game. Matthew's only shot at freedom is helping the police bring down Mr. K, the elusive mafia boss of the city. The only problem is that the detective he is forced to work with is the same man who arrested him years ago.

Masahiro Payne is everything Matthew hates: cold, calculating, and relentless. But their only hope for survival is by pretending to be a happy couple, blending in amidst dangerous crime, deceit, and power struggles. The closer they find themselves to taking down Mr. K's empire, the more they are attracted to one another, an affair too potent to turn from.

As their undercover mission spirals into a web of lies and hidden desires, they face a growing threat from all sides. But the greatest risk is the one they can't control-their own feelings. With every touch, every stolen kiss, the line between their fake relationship and real emotions blurs.

In a world of betrayal, trust is a luxury, and falling for each other may be the deadliest mistake of all. Can they survive the deadly mafia games or will their passion be their demise?
