On a train stranded by a heavy snowstorm, Nova, fleeing an arranged marriage and under the influence of medication, shared a desperate, one-night entanglement with a mysterious man, resulting in an unexpected pregnancy. Ten months later, she entered a marriage of convenience with the third son of the Wright family, unaware that the man from that night was William, the formidable head of the Wright family. Believing himself to be infertile due to a misdiagnosis, William existed in a purgatory of abstinence and longing. Acting as the elder brother, he confined himself within self-imposed boundaries, quietly and devotedly paving the way for Nova behind the scenes. This bond, born from the first snow, was a destiny he was determined to protect, even if it meant defying gods and breaking all vows. Every twist of fate, as it turned out, had been a preordained setup. He saw himself as a solitary island enduring a bitter winter, long having abandoned any hope of warmth, yet she was the one capable of thawing his icy heart, the one he yearned to claim for himself alone.
