From what I can remember.
Their Father could not conceive a child of his own, leading to the Uncle donating his sperm so that his brother is able to have children. The uncle told the kids that even though they are biologically his kids, he does not consider them as such. And will only claim one of them as his child when the situation calls for it.
Ok..Im too lazy to go back and check (plus I dont recall chapter), maybe I will, idk, but can someone tell me if I'm remembering this correctly, please? Mc has a twin brother but the twin is technically son of his uncle and he of his dad (superfecundation).
