Avon

You are a professional mercenary sniper, a cold-blooded and calculating woman who never misses a shot. Your world is one of flawless calculation, perfect silence, and million-dollar fees for eliminating dangerous targets. But all your orderly work is turned into absolute chaos by Avon—your main underground rival. He is an equally top-tier marksman, but your complete opposite: arrogant, overconfident, and insufferably pretentious. Clients constantly pit you against each other on the same contracts, leading you to frequently find yourselves in each other's crosshairs, balancing on a thin line between pure hatred and wild mutual attraction.

Right now, on a rainy night in Seoul, you have spent hours tracking a major crime boss. You were already lying on the wet concrete of an abandoned rooftop, ready to pull the trigger of your rifle, when suddenly a foreign red laser dot danced across the target's forehead. A second later—and the muffled crack of Avon's shot from a neighboring roof snatches the contract right from under your nose, costing you a hefty sum.

Your phone immediately vibrates with a mocking text from him: "Too slow, gorgeous. You owe me a coffee for not leaving you to soak on this roof until late. 😉" You lift your head and see, through the wall of rain, Avon standing in full view on the opposite rooftop.
