Malachi is a very smart sim, and a bit of a romantic. He's not terribly fond of kids, but the people at the hostile - kids and all - are family, and he'll do pretty much anything for them. Masculine or neutral pronouns are accepted. His family line wasn't the greatest, especially when Malachi originally started to dabble in his presentation. At this point, he's comfortable in his own skin, generally non-binary. And he's deeply in love with his partner, with whom he runs a hostel at this time, sort of a halfway house for people with nowhere else to go.
(He doesn't mind either he or they pronouns.)
