Fireworks Die, Our Love Ends

Lia Valencra, sole heir of a New York mafia clan, has a four-year secret romance with Cain, her adoptive brother and the family's intelligence captain. Driven by false rumors of his father’s wrongful death, Cain manipulates her love for revenge. By chance, Lia finds their intimate moments livestreamed to his men and learns her younger sister Ivy aborted Cain's baby. Shocked by the cruel deception, she agrees to an arranged marriage with Adrian from the rival Castellano family to gain backing. At the family anniversary banquet, Lia unveils solid proof proving Cain's late father was a traitor, crushing his motive for revenge. She dismantles his hidden networks and punishes all accomplices including Ivy and Sienna. Plagued with remorse, Cain begs for reconciliation in the pouring rain, yet Lia, now the legitimate family boss, rejects him firmly. She marries Adrian on equal terms and takes full control of the Valencra territory.
