Sweet Temptation: Big Sis Has a Soft Waist, and the Engine Roars

[Modern romance + wealthy-family power games + younger, unhinged male lead + racing god + fallen socialite + revenge and putting villains in their place + intensely sweet romance + both devoted to each other, happy ending] [Wild, unhinged king of the racetrack VS cold, thorny rose] Three years ago, on the night her family fell… After one reckless night, he gave a low, husky laugh. “Sis, how are you planning to pay back the interest on that ‘lifesaving loan’?” “Maybe you could use yourself as collateral?” Later, he became her biggest client’s handpicked “special security consultant.” He stuck to her side every moment of the day, even trying to claim the sofa in her design studio for himself. He was wild and impossible. She thought he was just a dangerous pawn on her revenge chessboard, and let him get away with his audacity and possessiveness. But when she finally crushed her enemies beneath her feet and stood in the spotlight to claim her crown, the supposedly cold-blooded “king of the racetrack” dropped to one knee and slipped a thorn-crowned diamond ring he had designed himself onto her finger, announcing to the world, “Gu Xi, my queen.” In a corner where no one could see, he tightened his grip around her ankle, his eyes burning with an obsession that would consume everything. “Sis, the crown is yours… and you belong to me.” *He was once the rejected son of a wealthy family, struggling in the mud. She was a swan fallen from the clouds, her wings broken. When they met again, he had become an emperor of the night, while she had become a thorny rose. And he loved every bit of her prickly nature.* *Shen Jin: “There’s no finish line on my track. She’s the only finish line I need.”*
