You have way more faith in the mangaka's writing abilities than I. Almost every arch since vol.2 has had drama and dubcon because one of the couples still has unresolved feelings for someone. unless Natsuki invents another couple for the next story she has to go back to mafuyu/uenoyama, and the best way to generate drama between those two is through Yuki.
Uenoyama is starting to get pissed while Mafuyu is daydreaming more about Yuki than being concerned for his actual/ living boyfriend. It's not hard to see where this is gonna go.
Is it lazy writing? Sure, but why start putting in the effort now. But who knows, maybe I'll be wrong.
Please I just really really hope your wrong … I have no faith in the mangaka writing since the last chapter and for a few things, I always end up disappointed …. Tbh but I still hope mafuyama relationship is not going to be destroy
Please I’m not gonna support an another sex scene like chapter 20 and 41
I bet Uenoyama and Mafuyu's first time will almost certainly be a little dubcon-ish now (shivering, crying and plenty of "wait!" phrases), based on every other couple we've seen.
But how to turn someone as sweet and considerate as Uenoyama into an asshole on Akihiko/Shizu's level? Simple: just make him incredibly insecure and jealous because he thinks Mafuyu's still in love with Yuki. The scene writes itself.
Yes, it's just a blatant copy of Shizu's arch, but the author has already been copying the same story twice now, so not like she's opposed to the idea.
And yes, I predict this arch too will resolve when someone decides to sing a song on stage.
