here's the gyst: their family is insanely rich. father owns a real estate conglomerate. jos here was the middle child. oldest son is inheriting the family empire, the youngest was the troublemaker. growing up their father was never around, mom was busy living the rich life so they were raised by nannies. jos was the only one that manifested powers growing up, but i imagine the siblings really grew apart as they all lived their own lives. the rest is pretty open as far!
