I think you should change your POV to make it less scandalous. She's just stanning the child version of "Abel Louvremonte", the hero of the novel she read. To take note, she has never gone beyond the line when she idolize Abel. She send proper gifts (you guys probs won't even dare to imagine what a traumatic fan gifts could be - a letter written with menstrual blood) and she only visited him on public places previously since you know - privacy.
You all are really making it really bigger than it seems. I know you all have a goodwill about it with how sickening a pedophile could be irl but you should also notice how Ayesha always put Abel's well-being first and responds immediately whenever someone abuse him. Did you forget how Ayesha treated Abel's injured feet while crying in the middle of the night? Or how she showers him with love at every given chance considering him growing up hurled with insults that affected his self-esteem. That's why you shouldn't take something by its cover and make a rash judgement towards someone.

she even explains her obsession with stanning too, that she just wanted to be loved in some way, not necessarily romantically. her love for abel wasn't romantic to begin with, she never expresses a dislike towards the actual FL of the story, hell she even wants to make sure they eventually meet. she knows Abel's tragic childhood and she just wanted to bring some light into it from the start. people are reaching lol

So will there be mpreg or will theirs be switched back?

We don’t quite know if it was merely the physical appearance changed (genitalia) or their reproductive organs changed (uterus, etc), but this doesn’t seem like the manga that would put something like mpreg. Honestly that started off as a fetish thing, and this manga is meant to be a wholesome story about coming to terms with your body and sexuality and accepting the changes. So tl;dr most likely no, because it would ruin the story

Since the small shrine moved to this other street and there is a banana there. It means a couple will change their genitals again but it doesn't necessarily mean our couple. Because they are walking on the middle frame whereas the shrine and banana are on the left frame.
Though the small shrine might not necessarily change genitals, because there is a male and female figure, I have a feeling that they are there to create coincidence for a new couple to meet or for couple to wish they last as a couple forever.
In the end it doesn't really matter whether they change their genitals back or not, as they say, they are happy they've met. And that matters the most.
I prefer the previous title lmao (づ ̄ ³ ̄)づ
