Robert and Steven have been inseparable since childhood, bonding over music, dancing, and late-night studies—so close that strangers mistake them for brothers. When Leah arrives in Remark town, the striking and ambitious visitor from another city disrupts their perfect dynamic. Reserved by nature, Leah opens up only to her cousin Menchie, who hosts her during her stay. Steven devises a calculated strategy: he'll pursue Menchie to position himself closer to Leah, hoping proximity will turn her attention toward him. But Menchie's heart belongs to Robert, and she refuses Steven's advances. As Steven watches Robert's subtle shifts in behavior, a dark suspicion takes root—his cousin has already claimed what Steven desperately wants. When Robert's intentions toward Leah become undeniable, Steven's jealousy spirals into something more dangerous. A contract marriage proposal emerges as a twisted solution, but with it comes tangled secrets, betrayal, and a mystery that threatens to destroy them all. In Remark town, desire breeds deception, and love becomes the most lethal weapon of all.
