I have one charrie who's mildly appropriate for a romantic type plot. Fynn

He's my vampire. He's a real sweetheart deep down but he's got a lot of issues opening up. He was a cow on a bloodfarm and got changed by a vampire who owned that particular farm (for a very arbitrary reason, too). Because of the drug treatments and his naturally laid-back personality, he never really dealt with the grief of losing his whole family and around ten years of his life (the process of growing up) to the blood farm. He's very nonchalant when talking about it, but he's got problems underneath all of that. Overall, he is a good guy, and he is romantically inclined because he gets lonely.
Otherwise, I have been contemplating making a character who is a double agent for the Insurgi and the Caedo >_>
And I, uh, love romance plots, if Nine and Dice are any indication. >_< But if the characters don't have chemistry I won't force it, you know? So if you liked either of those suggestions, we'd have to play it out and see how they interact.
Oh, Fynn is also a Caedo thief, so he's kind of part of an organization she opposes. The double-agent guy would be part of two.
