True story I encountered

A female colleague and a male colleague secretly got together for three or four years.
The most incredible part is,
the woman's husband still considers this man a brother,
and they eat together every day!
A woman married in 1994 and a man born in 1984, shortly after marriage, began this "underground affair."

During the day, they pretend not to know each other at work, and go home separately after work.
Her husband often pats the other's shoulder at dinner parties and says: "My wife is at the company, thanks for taking care of her!"

Why do you think they love each other so much but don't divorce?
Don’t be naive! It’s not love at all, it’s greed.
They want the stability of a family but also crave excitement outside, unwilling to give up either.
Who ends up hurt in the end? It’s always the one kept in the dark, foolishly thinking they are very happy.

Have you ever encountered such "actors"?
