After two centuries of living, Balthazar has realized a couple things about his attractions. He is a grey asexual, meaning he very rarely feel sexual attraction to people. That doesn't mean he doesn't engage in it, but if anything it's just to have physical closeness with someone when he's feeling lonely or something. Balty is also panromantic, meaning that he feels romantic attraction to any gender, and doesn't really have a preference either. As long as he feels emotionally drawn to someone, he's capable or loving them. At the moment, he doesn't have anyone but probably would be open to someone who is passionate about things. He wouldn't be particularly open about being attracted to someone, but he would be the cute sort of romantic, like leaving flowers or notes. Not that he'd really admit to doing any of it, but y'know. A student would be off limits for him unless they were much older, but other than that if it seems like an interesting prospect, let me know!
