Pieces of us

"In my world, a stiletto isn't just a high heel. It's a lethal weapon."
To the underworld, Agent Red is a phantom-a deadly, independent assassin who leaves no trace, known only for her striking split red-and-black mask and her signature, razor-sharp gold stiletto daggers. When she strikes, it's quick, quiet, and completely flawless.
But to Hyunjin, the cold and powerful syndicate leader, she is just Ayra: the quiet princess staying under his tight security.
By day, Ayra plays the perfect, innocent captive, blasting Enhypen through her headphones and writing stories on her laptop to stay out of the crossfire. But by night, she slips through the shadows to protect her freedom.
When a breathless confrontation in a rainy alleyway pits them against each other, an intense cat-and-mouse game begins. Hyunjin becomes completely obsessed with hunting down the mysterious assassin who managed to make him bleed-unaware that the predator he's looking for is sleeping right down the hall.
As rival empires clash and the tension reaches a breaking point, keeping her identity a secret becomes a matter of life and death. Will the truth destroy them, or will the girl holding the blade find her ultimate match?
