jinyao is Rourou’s father by genetics but Yi Yun is Rourou’s father because he raised Rourou’s. Imagine if a woman gave up her child for adoption and the child was adopted by another woman. That child would be the child of both parents even if they weren’t related to one of them by blood. That’s essentially Rourou’s situation in a sense. He is Feng Jinyao’s son by blood by Yi Yuns by other means
aww okay, thanks for explaining. Then i guess yi yuns embyro is that baby who jin yaos aunt got
yes , jinyao's aunt have Yi Yun's baby
So, is rourou both jin yao's and yi yun's son?
