Man, this is a weird chapter because Iemori, despite being just the densest, most oblivious guy ever, isn't really doing anything wrong here. Kanna is the one steamrolling in.
That said, god this just feels so forced and cliché ugh!
"Damn, no veggies!"
"Guess who has veggies!"
"Shit, I needed a mental reminder that I already like someone (who I swear I actually like, frfr!), I'm almost seeing how I'm being inconsiderate to her by keeping this goi-"
"Oh wow, a plot device that makes that completely irrelevant, who'd have guessed?!"
I have a feeling this will get a lot better once the 3 girls start to resent one another and we have some actual unforced, non-manufactured harem plot.
Also please more Mayu, she's the only person in this manga who's apparently not an idiot lol
