Hit On Me

Hitmen? In this economy? It doesn't pay enough for Vincent (codename: Mr. Noir), so he has to make pizzas to pay the rent. But Vincent's fortunes change when he's offered a chance at a million dollars to take out Dragonfly, the best assassin around and his hitman-work-crush. The catch? There might be something linking Dragonfly and the cute girl who he just agreed to live with. Source: Webtoon
