"Mary had a lover then, he went out to sail again...when he left her dead and gone..."

You were about to sing the bridge of your new released song at your concert. As you did not your husband entered the performance.

The song was about him, cheating behind your back. He was looking at you performing when he realized that the song was...about him, and the named Mary in the song was referring you

He face the ground and muttered to himself, "I'm sorry..." as he watch you perform.
