oooo i feel like the aunt made a deal w blondie’s dad side of the family or smth to take care of him in return for money cus him, his mum and aunt (assuming the aunt isn’t his actual mum) all have light hair but the cafe owner and the other guy that works there (probably his cousin or smth) and his dad all have dark hair
assuming the dads side is the rich one cus there were rumors of blondie being a chaebol it makes sense the aunt is putting on an act to get money cus she’s not part of the family, cus if mums sides rich then she would def get inheritance too, but if it’s dads side, then she isn’t part of the family, so smth probably happened to the mum and she suggested she would raise him
