In fact, although there is a name of husband and wife, there is no reality of husband and wife

Or nominally married, and everyone attended the wedding.

However, husband and wife did not do what husband and wife should do, but these are only known by husband and wife.

In ancient times, it was said that fame and fortune meant that although the couple were married, they never had sex.

Now, to say that there is no name is to express the majority of strange bedfellows.
