The wife committed adultery without knowing that the husband saw everything

My wife Chiharu's birthday. I couldn't pick up the cake I had pre-ordered at the store because of the long work hours, so I returned home empty-handed after midnight. However, Chiharu kindly said: “My feelings are enough, thank you.” I'm busy, but I feel a little happy. The next day, I finished work early, bought a cake and went home earlier than usual. When I was excited to celebrate my late birthday when suddenly, my wife had sex with a stranger.
