What if the wife is too ugly? I regret it now.

As the saying goes, having an ugly wife at home is a treasure. You have met a treasure now. Cherish it. Such a wife is a good wife as long as she is good-natured, considerate and reasonable. It's useless for a woman to be beautiful. When she comes home, she will think you are not pleasing to the eye, noisy and always cuckolded you. So be careful, brother.
