Punish the employee who stole things from the supermarket

A man works at a supermarket and he is in his forties but still alone. Remu Suzumori is different, she is a beautiful young girl who works with him and has a boyfriend. He always wanted this girl but had no chance because he was old and ugly and Remu was radiantly beautiful. One day, he happened to look at the camera at the supermarket and discovered that Remu had stolen things there many times. So the opportunity came, he presented that evidence to blackmail Remu, she came to his house and made love like a whore to hide her theft.
