Aren Sercia succeeded in finding the man who would one day become the strongest swordsman. Before the crown prince could take him under his wing, she registered him as her younger brother. Although they shared not a single drop of blood, she treated him more kindly than anyone else, raising him well. One day, he would surely save her from her bastard of a fiancé who killed her in her previous life, and she would also have him go to war in her father's stead. "From the moment I first saw you, I have never thought of you as family, my dear sister." His sharp eyes were filled with possessive desires. It was a beast that she brought in as her younger brother. (Source: Naver, translated)
