I think Kamijou realizing that Hijiri was sloppy as well (with women that is) because she was able to deduce who the black haired woman was to Hijiri, she might do fine if Hijiri leaves her to be like the black haired girl.
She's a strong independent woman (according to herself) afterall lmao. But yeah still, Red Flag.
Brooo, I'm such a sucker for stories about finding the one that got away, especially when they're childhood friends, kinda relateable, I'm so on board. Also the fact that they both kept the pictures and look at them from time to time, is mad adorable.
As for Sayaka, if she does continue to be in the story, I'd rather she get with the Senpai, than it be poly, since she needs some lovin' too, and they'd make a great pair tbh.
Everything in this comment, I agree with. LMAO I want Mai to see her already. She even has the same picture.
