I'm writing a story and I'm thinking about using
Rio and
Luna (after two dogs I had named
Ryo and Lunar who were littermates) for boy and girl twins.
Rio has brown hair and
Luna has black hair with blonde highlights, both have brown eyes and their cousins are the main protagonist and antagonist named
Vincent and
Cyrus. Their last name is
Alexander. So, what do you think? Do they sound good together or not?
