After the death of her parents, Y/N is sent to live with distant relatives at a sprawling manor hidden among the misty moors. Lonely and struggling to fit into the wealthy household, she finds comfort in the company of another outsider—Yu~ki, a quiet, enigmatic young man who was taken in years ago under mysterious circumstances. While the rest of the family looks down on him, Y/N sees the kindness hidden beneath his cold exterior. The two become inseparable, escaping into the wild countryside whenever they can and dreaming of a future where neither of them has to answer to anyone. But as they grow older, the gap between their social standing becomes impossible to ignore. When a wealthy nobleman begins courting Y/N, her family pressures her to accept a life of comfort and security. Yu~ki overhears only part of a conversation and comes to believe she is ashamed of him. Without a word, he vanishes from the manor. Years later, during a violent storm, Yu~ki returns. No longer the poor, withdrawn young man Y/N once knew, he arrives as a wealthy and influential gentleman. Yet beneath his composed appearance lies years of heartbreak and resentment. As old feelings resurface, Y/N finds herself caught between the life she chose and the love she never truly left behind. And on the windswept moors surrounding the manor, some wounds refuse to stay buried.
