Well it could be like in most isekais that she is her but lost those memories, it could be another lifetime for her and her soul came back to this world
Kinda like suddenly became a princess
Or it could be real Abella's soul is bound to this body or something
I'm assuming this vow goes over lifetimes cuz they used ancient language especially one of the ancient beast so considering there's magic in this world it couldn't be simple deceleration of love
Sorry I don't wanna turn this long I'm just theorising

No its ok! I like ur theory :D for me i didnt think about the dragon words much since if it was so ancient first ML the duke shouldn't know what it means but he reacted the moment those words got said and got angry so i just thought maybe its just a normal confession of love in their culture ╮( ̄▽ ̄)╭
We'll find out next chapter anyways but now i'm curious what will happen next ε=ε=(ノ≧∇≦)ノ
I mean, the past is past shes no longer Abella shes Aisha it's like if in ur past life u were idk, Leonardo Di Caprio would u still be Leonardo when u reincarnated? Would u have the same belief, and same love for ur past lover back then? You'd have grown up as someone else entirely, and just bcuz u and ur lover from ur past life had a promise then doesn't mean it would still apply to her reincarnated self. Especially since Aisha literally has a fiance now and is about to be married, 2nd ML better let her go
