Love was never part of the plan. But neither was falling for the mafia brothers. The Titicharoenrak family-a feared mafia clan disguised as a trading empire-thrives in the underworld, ruled by power, strategy, and ruthlessness. Sky Wongravee, the heir-in-progress, is a man of action, feared yet reckless. His younger brother, Gemini Norawit, is the brains behind their empire, strategic and dangerously charming. Alongside their stepbrothers, Perth and William, they are unstoppable. On the other side stands the Jirochtikul family, a prestigious business dynasty built on success, luxury, and unbreakable sibling bonds. Eldest brother Nani runs a renowned fashion empire, Est is a sharp-witted doctor, Santa dominates the influencer scene, and Fourth, the youngest, just opened a bakery that quickly became a city sensation. When fate entangles their paths, love sparks in the most unexpected places-a mafia heir captivated by a soft-spoken fashion mogul, a wounded assassin falling for a sassy doctor, a playboy strategist bewitched by a kind-hearted baker, and an enforcer meeting his match in a confident model. But in a world where love is a weakness, can they afford to fall ? Or will the hidden dangers tear them apart before they even begin ?

The Jirochtikul siblings are chaos incarnate, balancing their family's high-profile businesses and underground car racing empire. Amidst gala nights and roaring engines, romance sparks when Fourth, the sassy and mischievous lawyer, sets his sights on the calm and composed hotel heir, Gemini Norawit. Simultaneously, William, the rebellious racing prodigy, finds his match in the enigmatic Est Supha. As love ignites across their clashing worlds, these heirs must navigate thrilling rivalries, family expectations, and the exhilarating race for their hearts.
