He is quite blunt and values honesty and fairness. He is stubborn and while seeming cold and aloof cares a lot about other people, but doesn't show it. On terms of sexuality I'd assume he's mostly hetero because of the time,  but is more of a demi-sexual (I don't know LGBTQIA terms to well, so pardon me if I'm incorrect) a person who will only experience romantic interest after a deep bond is formed. He is very loud and passionate about certain things: such as family, justice, and keeping a timed schedule for when he waters his plants. Despite his weird nature he attracts many people with his sense of justice and understanding of how to deal with them in certain emotions. I'd expect him to have a slightly deep voice, that is purposely paced so people can understand him, hence the caring about other people thing.
