Alrighty, I'm just gonna constantly dump random ideas for him here. Feel free to volunteer your characters for them if you really want to. Or suggest other plots for him!
Raf has actually been betrayed multiple times, especially back when he resided in the Feral Lands. Naturally he closed himself off after a while, and his carefree attitude is really just a defense mechanism. I was hoping that he'd become really good friends with someone and therefore become super protective of them. Like... "I'd take a bullet for you" protective.
Pretty self-explanatory. Basically, they can be either gender and any age. Raf generally dislikes kids, so him adopting someone as a kid brother/sister would be adorable.
