That makes sense
that's the thing with Chinese cultivation manhuas/novels. reincarnation trope is not unusual.
They were both reincarnated, but that's not the reason AoAo doesn't remember meeting Ryan before in his present life, back when they were kids. Someone erased his memory of Ryan from the time they were kids because he and Ryan were not supposed to meet again in this second lifetime (because of the tragedy that they had caused in their first lifetime together), yet they did meet again in this second lifetime, when little AoAo went to little Ryan's mountain, so they erased his memory so that the story of their past life wouldn't repeat itself in this one.
Thats makes sense... It is sad only little ryan remember aoao ;-; and There’s also aoao brother and that god....his brother doesnt seems to remember either
I wonder if they were reincarnated thats why they cant exactly remember their past
