When it comes to the scandal i really dont want it to happen like in the pre serialisation, honestly i dont want the manga to end in the near future, not because is good but because takeda super wasted so much time, like we are on chapter 101 and non of us and honestly it isnt hard to imagine JPBros thinking the same, want agawa to win, after volume 2 she started to become unlikeble, she has been either the main reason or partialy involved in every bad thing that happend to gotou, their relationship isnt going to get fixed in like 20 chapters realisticaly, let alone enter into a romantic relationship, and honestly the reason why gotou fell in love whit her in the first place was because of her kindness, kindness that not only she hasnt shown but that other girls have. Like imagine if other romance series did something like this, your main heroine, like stops being relevant and when she returns not only does she have limited screen time but also she stars more drama ans almost ruins the main relationship of the series.
My second reason is because i think in a way the scandal already happend, ironicaly both for agawa and for gotou, for agawa was everything that happend after summer break, esentily it is mention that she "looks sad" just like her mom mentions it in the pre serialization, there is also the fact that she loves gotou but feels guily so she keeps her distance, hell even her relationship with erika could be a mirror her relationship with yuki in the pre, both of them are fake so, for gotou is the introduction of kiyomi, it stats with a dream secuence, like in the gal jk ero manga, and he starts fucking kiyomi without a care in the wolrd, and he gets caught, its just that this time he doesnt get expelled. Now i think this point in particular could be me saying nonse but honestly, idk i enjoy trying to make sense out of this mess of a manga.
When it comes to agawa she is aware of how bad he is doing, she has been aware sinse summer break, but she hasnt changed course she is removing herself from the situation, probably just for her own peace of mind, and the worst part is agawa is doing it subconsiusly.
i think that what is going to happen in next weeks chapter is probably their intervention just happening earlier, and probably we will get to know what is worring gotou and something tells me that agawa wont like the answer but like always she wont really do anything when it mattered the most and that will trigger the flashback, at least in my opinion.
