Atonement, For Your Cruelty summary: Male Protagonist: Oscar von Reichinhardt, the head of the Marquis Reichinhardt family, possessing black curly hair and blue eyes. He owns the railroad traversing the Norfolk continent and the continent's largest steel company. He is capable of doing anything to achieve his goals. Even if ordered to kiss the back of an enemy's hand, he would do it if it helped him. It was because I acted with extreme efficiency that I was able to rebuild my family from complete ruin. That is why I could not bear the pathetic self for succumbing to such an absurd temptation, and I cannot forgive the woman who made me this way. Female Protagonist: Han Seo-ah, a mixed-race individual with brown hair and eyes. From the moment she could remember, she was always an outsider. Because her appearance was different, it was impossible not to know that there was something wrong with her birth. The starting point of the sin was the moment she was created. Therefore, she wanted to atone for it, even if it meant sacrificing everything she had. To her grandfather, and to that man whose mere sight made her heart flutter.
