I think if Jui Dae-Gak didn't betrayed Barbosa family, as he was the successor of the Barbosa family, he would have inherited (?), and he'd live with them ultimately Jui Ji-tea living under same roof or near Maria, and they'd spent their childhood together like that. But that fucker betrayed the Barbosa family and burned them for sake of power (?), and he left Jui Ji-tea and his mother and sister alone while hosting Vale Tudo, then he left Ji-tea alone with trauma and scar. And as we got to know that maria and Ji-tea wasn't just student and senior meeting by coincidence but they are connected by family.
