Provide for the subordinates separately with the wife and the ending

I was promoted to department head of a construction company in Tokyo when I was very young. I even married a colleague who was known as the beautiful angel Fumino. I thought this perfect life would last forever, until something happened that turned everything upside down. I had a lazy subordinate who didn't believe in marriage. In order to show him how happy marriage can be, I suggested that he spend three hours alone with his beautiful wife. That evening, I invited him to have dinner at my house, then made up an excuse about work and left.

Three hours later, when I returned, I saw the two of them chatting happily, and it seemed like my plan was working. A few days later, the subordinate wanted to experience being alone with my wife again. Out of curiosity about what they did when they were alone together, I secretly placed a camera to record everything. When my wife went out for tea with a friend, I watched the video from the previous day. And the scene on the screen made my whole world collapse...
