My Marriage Is so Ridiculous

My wife, my wife, my grandpa has a marriage with a snake spirit. My wife... Grandpa has a life-and-death relationship with a certain soul. In the family tree, there is always a certain ancestor who has had different fates with some strange beings. Well, what? You ask me what's going on? Now I have probably become the savior of a certain soul, the savior of a certain vampire girl, the husband of a certain ice queen, and the creator of a certain mechanical life, etc. I have to say here that these fates are really outrageous.
