Shoko is forced to take over her father's massive debt and enters into a contract to repay it gradually while living on-site. However, this contract includes unimaginable conditions. She is subjected to a strict rule of living completely naked, stripped bare in front of her father and forced to remain nude every day. She is compelled to provide bodily services to visiting guests, made to perform cleanup blowjobs after the master urinates, and dragged into forced porn video shootings. Ultimately, she experiences the ultimate humiliation—reaching orgasm in front of her own father. This work portrays her struggle to endure these extreme conditions and the profound transformation of her inner emotions, delivering a shocking narrative layered with intense human drama.
