The uke got taken in by a family and felt really guilty toward them, so he worked hard to save up a bunch of money to pay them back for his school fees and he was going to resign from his job after. His (younger cousin/brother?) confronts him about it. It was kind of a toxic couple cuz the younger cousin/brother was super pushy. If anyone recognizes it, I'd be super grateful!
