Sai Ramirez is the kind of girl everyone underestimates. Clumsy. Makulit. Medyo tanga. Mahilig sa kulay purple. Laging may kalokohan at parang walang seryosong problema sa buhay. But behind her loud laughter hides a painful past... and a revenge she's been planning for years. JB Alcantara is the cold and ruthless heir of one of the most feared mafia organizations in the country. To his enemies, he's a monster. To his allies, he's a leader willing to kill without hesitation. His right-hand man, Ice Villaruel, never questions his orders, while his closest friends - Jekhar Dela Cruz, a notorious playboy, and Lhanz Moreno, the joker who spends his free time playing Roblox -always have his back no matter how dangerous the mission is. Everything changes when Sai accidentally crosses paths with JB. What starts as a series of funny misunderstandings slowly turns into a deadly game involving mafia wars, betrayal, hidden identities, and secrets that should have stayed buried forever. As love begins to bloom between two people standing on opposite sides, the truth slowly comes out. Sai isn't as innocent as everyone thinks. She entered JB's life for one reason... Revenge. But what happens when the man she's supposed to destroy becomes the only person willing to protect her? Will love survive in a world stained with blood? Or will revenge pull the trigger first? In a world where trust is expensive, betrayal is everywhere, and mercy means death... Love is the most dangerous weapon of all.
