A small-breasted girl is imprisoned and trained. Unable to pay the rent, her toxic parents put her to sleep with sleeping pills, and when she wakes up, she is tied up and deprived of her freedom. When she finds out that her mother, whom she trusted, has betrayed her, something inside her snaps, and she is reborn as a sex toy for a bald middle-aged man. A record of a girl-raising enthusiast who imprisons an innocent girl for seven days, trains her, and raises her as a sex slave.
