I don't see them in an exclusive relationship. And if they do, it won't end well.
We can't call what they have love or something near the definition (after all, remember he said he fell too easily for people he has fucked). Gotou is more on the possesive side than genuine feeling (the chapter prove it for now). And I don't see him to be able to shutdown Agawa for example.
In a extreme case, It'll take an infinite stretch to ask Akito to be exclusive to him while he can bang anyone. Remember that she's on the slut road to take back Gotou because she felt inferior to Agawa and Pres.
More, during the festival, she was dejected after Gotou said he was on date with the pres. She was hurt after that. Sooo, even the multiple sex partners road is hard to conceive rn because of that.
I can only see them go their separate way, whatever what form their relationship will take. But we'll see in the near future
Someone had mentioned this to me in the reddit discussion of this chapter. Takeda most likely added Akito, Inukai, and Shina to add more drama and deeper NTR to the story, there's no telling where it'll go next. She could be slutted out or not, he (Takeda) could just keep the tension and resolve it either in a wholesome manner, or in a not so wholesome manner, and end up losing lots of readers because of it. Personally I hope Inukai doesn't try to get the last laugh, but I dont see anything good coming from this
That person i responded to mentioned a good point, which is that Gotou may still follow his doujin lore and end up with Agawa, which means Akito MAY not be endgame 😔, that's a saddening IMO, but if I'm being realistic here, Gotou being with Akito isnt likely to happen, though imo I would want that to happen in some form and for Akito to atleast have a wholesome resolution. Because Takeda may still be going with the doujin ending, this gives him the perfect reason to slut Akito out😭, simply making her a heartbreaking piece of the plot😢. Hopefully its different though🤞.
The Doujin doesnt have Inukai, Shina, nor Akito in it, I scrolled through the doujin
here and saw a page with a girl who looked like Akito, but there was no dialogue, no introduction, nothing. Gotou didn't even acknowledge her all that much. So technically, Akito wasn't a character in the Doujin. It's because of this that I think we may get a different/alternative ending. it'd likely still stay true to the doujin, but with major differences. Though there are still some similarities, like we've seen pages 148 and 146 in the serialized manga
Because those three characters are now in the series, it's practically a completely different plot now, though they are there for plot reasons, definitely to add more drama to the series. I'm hoping for a different ending and wouldn't even mind Gotou being with both of them in some way, but this series doesn't have the harem tag, so it's highly unlikely😔. Just like you, im also rather interested in seeing how this will turn out, nervous, but interested. Akito wants to be exclusive, maybe she'll agree to some "arrangement", we saw that she was okay she being able to hang out with Gotou in chapter 60, but things change. But if she has been slutted out then Gotou may not look at her the same, and she'd end up being addicted to doing it with other guys which would be the tragic path.
