Although there is an age difference, Tsukasa was enjoying a luxurious life with her kind husband and a smooth sailing life when she received the news of his death. What plunged her into further misery, in her grief, was the fact that she had never known before that her husband had debts. With no way to repay them, she was played with by him under the pretext of his debts. Even though she tried to refuse, the huge debt kept coming to mind. As she was violated as he did to her, before she knew it, her body had been reduced to that of a sex slave who could not live without a man's penis.
