Brandon's family weren't exactly very accepting of his differences. When he started wearing clothes more meant for females than males, and getting into makeup (which, he'll have everyone know, he's very good at), his family about had a cow, and eventually gave him an ultimatum. Drop the crap, or get out of the house and don't come back. Brandon had no interest in being someone he wasn't again, and just left.
He made it on the street for a while helping drag queens and even random female Sims he met on the street look and feel good about themselves; he's kind of an amateur makeup artist in that regard, but it wasn't really what he wanted to do with his life. Ultimately, he met and befriended a man named Surya, who sort of adopted him and got him a place to live. It wasn't a great place, but it was a decent one.
Some time later, Brandon decided he wanted to found a shelter for LGBT+ Sims, a sort of halfway house for them to live in until they got onto their feet, but he couldn't afford it. Surya later introduced him to Kassander and Sandalio Giovanni, who decided to invest in his idea and gave him the money to get started. Casa di Colori, the house of colors, was established and built a few months later.
It's been a few years since then. Brandon met and started dating Malachite, got a calico cat, her name is Penny because the first thing she played with was a penny, and built a new family to replace the one he lost. Brandon's doing pretty good for himself.
