Well, I'll start by sending you this, but if that doesn't work out I'm willing to try something else or hear one of your ideas.
Yes, although technically you're not supposed to know that. Your character knows nothing about the assassin, not even their name or gender. That said, if there is any romance at all, it'd be a very slow burn. Your character would start out hating my character, afterall.
By the way I gave you a huggle.
