This is because the accident happened while 'Sion' was having an affair, and using insurance would risk her husband finding out about it. The helpless 'Shinon' decides to do as the man says and guarantees it with her body. She responds to the man's demands by urinating, masturbating and spanking while enduring her shame. The man's behaviour gradually escalates and he begins to toy with her, degrading her. No one knows what happened to 'Soul Sound' afterwards...
