Shiba Miyuki is the next heir to the prestigious Yotsuba family, a family of magicians. To her, her love for her brother, Tatsuya, is absolute; it goes beyond romance or sibling love. However, her family makes a cruel decision about her: to marry her older, ugly, overweight, and powerful uncle as a tool in a political marriage.
All for the sake of protecting Tatsuya's future. Miyuki prepares herself to be a "sacrifice" and accepts her fate. Before her wedding day, Miyuki's body is toyed with at the mercy of her uncle's desires. At school, in deserted places, and in his room at night. Miyuki continues to endure this humiliation, her feelings for her brother in her heart.
However, the man's relentless and persistent caresses imprint an unknown pleasure on her body. On her wedding day, clad in a pure white wedding dress, Miyuki pledges eternal loyalty to the man who will become her new master. Her eyes wavered with a complex mix of love for her brother, hatred for men, and the pleasure she had been taught. Her hell had only just begun.
