Not sure about that one yet, it could be either one, but the fact I do know is it seems both parents loved both Ao Gu and Ao Yue/Xuan Yue very much, even if the dad was forced to let that curse get Ao Yue and had to pretend not to care about him in order to be able to secretly send Old Jin to take him away, just so that he could have a chance to be free and maybe even someday find a cure.
Where/who is old jin in the present day timeline (unless he has passed?) and how did ao yue get reincarnated into ao ao when their mother passed when giving birth to him? Did she give birth to him two times?
