One night, Oscar von Reinhardt found the key to a safe he had long searched for — brought by a woman unlike any other. Her tearful eyes, naive demeanor, even her name irritated him. He wanted her out of sight. Yet no matter how many insults he threw, she kept approaching. "I want to be by your side." Too absurd to be sincere. Too pathetic to be temptation. And yet — on those small, soft palms, Oscar found himself played. So I will hold you accountable. Cruelly. For never once being sincere with me. Han Seo Ah has been an outsider her whole life. Her mixed blood, her very existence — all felt like sins to atone for. She came to him seeking redemption. He came to her seeking answers. Neither expected what came next.
