Congratulations on Your Wedding

The story has absolutely nothing to do with the title. Swordsman top x emperor bottom, childhood friends, separation and death, then a reunion later on. The characters are hard to describe. The author seems to have left their brain behind, has completely twisted values, and writes so badly they might as well have left the solar system. There isn't even an outline. It's an idea that's been kicking around for ages, and the story could be abandoned at any moment. Read with caution.
