I work overtime late at night with my favorite female boss.

I happened to see it. The female boss I admire, Yokota-san, and the department head, are in an affair in the workplace... I have no courage, so I have to do something like this and I will never be able to hold Yokota-san. This is a chance, I put my bet on it. "If I told the manager's wife about this... what would happen?" Yokota looked at me with a confused look on his face. ...I was thrilled. And from this day onwards I ended up working secretly late-night overtime with her.
