Anime romance yaoi monster boy roleplay

Hey I'm kinda wanting to do a long term yaoi roleplay with some plot and some smut as well as focused on romance!

You need to have watched this anime to roleplay it.
Please nothing to off the character.

I don't mind if you want to use a oc but I'm more of wanting to do oc x canon character.
If you use a oc I will do your oc crush and you do mine.

The anime that I am currently wanting to roleplay are:

•Mha.
•Black butler.

In real life gender dosent matter)

Ok now for the ideas mostly relate to a human character becoming a not human creature or if they already were like this but didn't want to be found out.(and maybe some genderbend who knows?)

Maybe we can spice things up with stuff like heat??

But yeah lemme just stop rambling and put the info already:

1: the oc of mine was someone from a modern world that got trapped in black butler,things were going fine for then,they became an earl after their story becoming a very popular best seller.
(If you want our ocs to know each other or be friends it's up to you)
But they have a secret,what happen when their crush comes to visit them at the wrong time?or find that out.

2(mha): the character does have a quirk related to this that ends up evolving itself in a rather different way then expected or simply that they get hit by a temporary quirk that transforms them.

((Just some ideas))
