I can't be your friend (can't be your lover)

On the outskirts of Gotham exists a no-name village where a no-name man resides. A man who has no purpose except to challenge what lurks in the darkness near the forests, a skittering shadow of something-someone moving faster than the eye can comprehend.That is until the man gets an uninvited guest who calls himself Batsy, insisting it's not a nickname. Alt: A royalty au no one asked for where everything is pretty much the same except bruce wayne is a prince (and also batman at night) and joker is a lowly criminal in a village.
