She's in a sequel story, except with extra twist.
So first of all, mom is kinda insane but not in the way you'd expect.
Basically during her time, mom also met with a reincarnated game heroine person, and even have a notebook written by her that clearly details something a person of her status should not be able to know.
Kinda skimmed that bit, but basically mom helped the heroine get to her target, then the heroine got greedy and want to try for reverse harem route since that's supposedly a condition to unlock the hidden route.
Shit happened and heroine died.
And mom points to the last page of the notebook, listing the cast of the sequel game that the heroine wrote down but since it won't affect her life she's like eh whatev.
On that list, is "Commoner Ashley" as one of the selectable protagonist.
Ashley also met the other protagonist, who is the reincarnated person.
So mom was saying how she intentionally left noble society, became commoner, and gave birth to "Ashley" to try and twist fate or something.
Although from what mom have seen, it looks like Ashley has been in the 'protagonist' spot of the plot
Then Ashley told mom that 'uhh, the story I heard from the other heroine...is different'
Basically everything her mom has done, is actually the sequel's backstory.
Mom didn't take that well.
So now I'm curious about what was the last thing the other heroine said to Ashley (since the other one seem to have disappeared/died as of this chapter)
