Can trust truly blossom when the lines of honesty are fatally blurred?

In a world where every fight is rigged and every debt is paid in blood, Ko Kyungjun refuses to play by the rules. A boxer trapped in the underground circuit, he fights not just for survival, but for something he can't name something slipping through his bruised fingers with every match. Yoon Seo was never supposed to be part of this world. She belongs to Minho, Kyungjun's best friend, the one who pulled him into the underbelly of the city. But she keeps coming back watching, worrying, crossing a line neither of them should. When stolen glances turn into something more dangerous, and Kyungjun's defiance makes him a target, the ropes that once held him steady now feel like chains. In a game where there are no second chances, he must choose: fight for a life he may never have or walk away before he loses everything including her. The characters are from kdrama called ''night has come'' but the story is completely different .
