NKKD-196 This time my wife (28) was stolen by a part-time worker at her job (20)… → I’m so frustrated, so please release an AV with this.（NKKD-196）

This year, when my eldest daughter started going to kindergarten, my wife started working part-time about four times a week to help with the family budget. Until then, she had been a housewife raising children, so I thought it was a good thing that I, as her husband, was able to help her with the family finances when she seemed to be enjoying herself, and she smiled. I was watching. However, recently, her wife says that she works part-time at the same workplace, and seems to be drinking tea and chatting at our house with a young man about the size of a pigeon.
