Oh shit
Damn, Mimika. Kiddo's beat you to it
Ofc, just like ch9, "does she?? Or does she not...?" is still subject to debate. We don't know if Yuzumori means it that way, tho it'll likely be clear in the next chapter(s).
Personally, I feel like it could easily be "yes, she does", and the author had it end like that just for the lolz, and keeping her readers hooked. But ofc, it could also have been written with the ambiguity because we can't even tell for sure if Yuzumori understands it fully herself.
Hm, I wonder if it isn't a little early for a confession. Yuzumori being jealous is like, a good sign of something, dunno if she realises it herself/meant to be or didn't care if she was obvious with it, but it's quite a jump. I'd like to know more of Yuzumori's perspective/feelings, what we know of her is still limited.
But yeah, could easily be "yes she does" or "no it's just platonic", I'm not sure what to expect from this sort of plot, I've hardly ever read fluffy age gap stories with one of the characters being a high school student and the other being so young
