Nah, considering her previous interactions with Yuugo, I think the fact that he was duped by Yashin and he’ll likely be around to help Youko kill him will absolve him within the narrative.
Yes, all this evidence of Gotou's accidental rise in social standing is priming Shigechi for the moment when Gotou finally breaks down and straight up tells her that she's the only girl he's turned on by. Shigechi, who clearly likes Inukai, but not the fact that she'll never be his number one...
Holy hell, slow down there NTR obsessed speed readers, Inukai is precisely who they’re talking about because of the shit he pulled with Akito in the last arc. I know I like to give this series more credit than it’s probably due, but even then it’s not exactly a complex story to follow.
I think the point of Akito being introduced to Shigechi as a man stealer is setting up a later rivalry for Gotou’s affections. See, if it pans out that Shigechi cures Gotou’s ED via affirmation of Gotou’s sexual abilities, the catch will be that Shigechi will expect or even demand exclusivity...
Time for chapter 79’s summary
The humour is that while Gotou is wracking his brain about getting with Shigechi, Shigechi herself is increasingly unable to stop thinking about and intersecting with him.
Well he’s not the one getting cucked even if Gotou bangs Shigechi, because he plain doesn’t give a shit about her any moreso than any other fine piece of ass. Just like he wasn’t being cucked when Gotou banged Agawa (who also banged Inukai beforehand). He’s obsessed with Shiina, and no other girl.
My prediction is that Shigechi will be oddly touched by the fact that Gotou is obsessed with her in much the same way Inukai (the boy she’s tsundere for) is obsessed with Shiina and that’ll be Gotou’s in. If anything it’s Shiina and Akito that’ll get NTR’d in this arc.
Quite the sticky relationship web we got going here. Gotou’s with Shiina (and Akito), but only desires Shigechi at the moment. Shigechi seems to like Inukai in a tsundere kind of way, but doesn’t like the fact that his main goal is clearly Shiina and not her. Shiina herself probably likes Gotou...
Who knows, Shigechi herself seems like she may actually like Inukai, but not the fact that he’s such an upfront pervert who clearly desires Shiina over her. Maybe if she learns that Shiina’s man Gotou only has eyes for her, she might be touched enough to give him a shot.
