Actually it is like having two personalities in one body .
Ryan is physical reincarnation of xiao jifeng (the black haired one in prologue ) .
One personality is the cute little dragon aoao met years ago in mountains and was waiting for him .Aoao doesn't remember him bc his brother erased his memories
but it is not bc big bro raped gramp .Infact aoao doesnot even know that gramps
& bigbro know each other it is bc of reasons related to ryan & xiao jifeng which is still not disclosd yet
Another personality is xiao jifeng himself who takes over ryans body
Both xiao jifeng & ryan loves aoao or say jifeng loves aoao & his past self xuan yue obsessively.
Aoao is physical reincarnation of xuan yue .
Xuan yue was powerful black dragon whose pearl was taken away from him .
His soul was assimilated. He reincarnated as powerless green dragon in this life bc lack of pearl ie the mystic pearl or the pearl of xuan yue which is now in ryan's body .
Ryan reincarnated as a black dragon (the form of past aoao/xuan yue) the person he loves but killed (as shown in prolouge) in present time .
And Ryan personality doesnt know anything abt jifeng or xuan yue or that the pearl own in his own body so whenever jifeng takes over his body he becomes confused & thinks he is suffering from some mental disease so he takes medication from jules .
It is hinted that big bro knows abt aoao & ryans past so he makes sure that ryan stays away from aoao
Jules likes ryan so he wanted him to loose his memories .
plus there's this curse Xuan Yue put on Xiao Jifeng
Yeah thanks lmao I didn’t know how to explain that in words cause I felt like my summary was all over the place
Ur Rt I forgot about that
So basically Ao Ao is a green dragon who’s powers aren’t that strong and he hasn’t grown ever since he was little and came to earth to find the dragons pearl or something like that if he finds that pearl then he will become stronger but Ryan is a black dragon that still has his past live soul in him and present Ryan and past Ryan share bodies. present Ryan remembers Ao Ao from when they were kids but Ao Ao doesn’t remember him because I think his brother wiped his memories so he wouldn’t be mad that he raped the dude with glasses (I think he erased his memories only around the time he met present Ryan which was the time the brother raped glasses) and his own (because he didn’t want to remember that he raped the brown haired dude with glasses) but past Ryan remembers past Ao Ao (cause they were lovers in their past life) and he and present Ryan both want Ao Ao to remember them but he can’t idk and now since past Ryan keeps interfering with present Ryans life his old friend Jules is making sure past Ryan doesn’t pull any crap cause the medication that Present Ryan used to keep away past Ryan is bad for him so it’s kind of like MPD but he can remember what happened when past Ryan was in control there still is some confusing parts and some things that I still don’t know how to put into words but I hoped this helped please ask if u need more answers or something and thx uploader
