The man who called a delivery health girl home after a long time. He had seen her somewhere before, but he couldn't quite remember. 'She looks a lot like my brother's fiancée,' he thought, and with a feeling of disbelief, he asked her to send him a photo... Sure enough, this delivery health girl was his brother's fiancée, who was scheduled to get married next month. The perverted and cruel younger brother, using this as a reason to blackmail her, toyed with the delivery health girl, who would become his future sister-in-law, and thoroughly enjoyed impregnating her.
