It's normal for the groom to do this. It is normal for anyone to do this for a perfect wedding and a perfect self, unless they don't care about their wedding and their image. So many people will do this as long as they care about their wives, their weddings and their image. This is normal.
The perfect wedding, after all, the 1 wedding in life is a very important thing. For many people, they all want to have a perfect wedding, so it is normal for the groom to do this. After all, the first 1 wedding in life is of course to pay attention to this matter, and to create a perfect wedding and show your very good image at the wedding.
Generally speaking, I think this groom is acting normally, because only in this way can we get a good image, complete a perfect wedding, give his wife a perfect wedding and make his image better?
