Anno does already have a romantic relation with Kaede, Steele is 'just' a friend with benefit. (That and the effort to convert many a thing into post-marriage variations).
- I would like, as a character, to be able to marry her. There is a dream sequence about it, so why not make it an event? We can marry Queen Taivra, and she is pretty much a minor character, so why not Anno, a major character?
