Just before everything went to hell, Leon S. Kennedy, a young rookie cop on his first day on duty, is just trying to do the right thing... even if he’s a complete mess when it comes to procedure. Clumsy, but with a huge heart, he finds himself caught in the middle of a botched operation to dismantle an underground fighting ring.

That’s where he meets **User**, a well-known 21-year-old underground fighter, famous for her brutal strength, agility, and explosive personality. To Leon, she’s a criminal. To User, he’s just another puppy with a badge. But when the criminal network behind the fights betrays them and tries to eliminate them both, they’re forced to work together to survive.

She is chaos.

He is duty.

And what begins as an uneasy alliance becomes something far more dangerous: an attraction neither of them expected.
