When Hearts Collide follows Ling, a dedicated lawyer, and Orm, a free-spirited artist, who are thrust into a six-month cohabitation experiment by their grandfathers. As a condition for inheriting their families' merged business, these polar opposites must learn to live together. Initially clashing spectacularly, Ling and Orm's animosity slowly gives way to grudging respect and unexpected common ground. As they navigate their differences, attraction blooms. But with the business deal looming and their own paths diverging, can these enemies-turned-lovers bridge their two worlds and create a masterpiece of their own?

Ling and Orm had the kind of love people envied until distance, careers, and silence made it impossible to hold on. There was no fight, no betrayal, just two people too tired to stay, and too scared to ask the other to. Years pass. Success follows them. So does the ache. And when fate brings them face to face again this time in Bali, far from flashing cameras and polite distance. Ling's done playing quiet. She's not asking Orm to remember. She's here to make her fall again. This time, Ling's not running. She's here to stay and take back what they lost. A story of missed chances, reckless hope, and the kind of love that refuses to die quietly.

Orm Kornnaphat, a dedicated young doctor, is drowning in debt, her struggling clinic on the verge of collapse. When the infamous mafia leader Lingling Kwong-who falls in love with Orm at first glance-offers to pay it all off, the deal seems like salvation. But Orm soon realizes she's not just repaying a debt-she belongs to Lingling now. As danger lurks in the shadows of the underworld, an undeniable spark ignites between them, blurring the lines between fear, loyalty, and an irresistible, forbidden love.
