hahaha ,I did a search related to the painting, and I suppose the man looks like that because he realizes how foolish he was.
To be honest, when I read about the painting and saw that expression, I immediately imagined the story, and I also laughed a lot while writing it. Some men don't think when they see a woman; they don't know how to be alone. I learned to be alone because of my work at home, and regarding letting myself be swept away by the beauty of some women, in my modeling work I'm surrounded by very beautiful women, but some are too vain. They're intelligent, but looking at themselves in the mirror so much seems to affect them, hahaha.
You already know that I'm a very sincere man, that's why my comment is too.
