Wow. You remind me of myself. Magic the Gathering, Fire Emblem, MLP, even TWEWY. I haven't seen too many people asking for those. Is there something in particular you are craving right now because I'm interested in seeing how things could go in an rp with you. ( I'm also a big fan of love/hate relationships). At the moment I'm craving more of a general setting with original characters than a fandom, although I could work with whatever you like.
To give you a feel for the kind of settings I do, here are some I've done in the past:
Gangster/Kidnapped Rich Kid
I really only play MxM, which sometimes is sad for me because I want to do MLP but there's no fodder for me there. :) We can talk more in PMs if you are interested.
EDIT: I checked out your plot ideas section and you have some interesting stuff. I might be interested in a Jace/Soren one-shot, but I like longer rps for the most part, so we could perhaps do two if you wanted? Just let me know.
