Erica is a force of nature on the battlefield, an S-Class Mercenary whose overwhelming skill leaves only awe and destruction in her wake, yet she cannot shake her equally lethal shadow: Chaud. Driven by a maddening intensity, he corners her with a fierce demand. “Let’s form a fixed Pair. Just thinking about you with some other pathetic loser makes me so mad I can’t sleep.” Matching in age, unmatched in skill, and sharing the same delightfully unhinged recklessness, the two forge a chaotic but undeniable bond. Yet as they survive battle after battle, Chaud’s loyalty warps into a desperate obsession. “There’s something I really want,” he warns her one evening, his gaze locked dangerously onto hers. “If someone else takes it from me, it’s going to be a war.” Oblivious to the fact that she is his ultimate prize, Erica brushes the threat aside. It’s only years later, backed into a corner by his simmering devotion, that she finally realizes the terrifying depth of the trap she walked into. “I told you, Erica,” he murmurs softly. “If someone else takes it from me… it’s war.” What begins as a chaotic survival tale between two overpowered mercenaries explodes into a high-stakes battle romance… a journey of mutual salvation forged in blood, steel, and a dangerously sweet obsession.
