Is there a word that doesn't match but is happily married?

There are many people who don't agree with each other but have a happy marriage. This eight-character is handed down from ancient times and is very idealistic. You believe it is good. It doesn't matter if you don't believe it To put it bluntly, marriage depends on people and how much you are willing to pay for each other. See how much you are willing to change for each other. Marriage is the mutual understanding and protection between the two sides, in order to go on. It's a person's problem, not a figure of eight.
