I legitimately thought Haru was gonna try and get between Miu & Akane as well.
Maybe I'm also a bit prejudiced toward her because of how possessive she's been acting over Yuka.
Anyway, the actual attempt at reconciliation between Ai & Rura classes was actually great to see. I don't think it's all gonna be magically solved just like that, but this was an honest effort, and the fact that Haru & Miu did it together, with the former being the "liaison" and the latter being one that Ai class actively wanted to kick out in the first place, might make Ai class a bit more receptive to warming up to the rest of them and not being so cold and haughty going forward.
Also Izumi explaining to Marin that Yuka actually does like Mitsuki was great. Didn't realize Marin hadn't clued into that, but she seems to be "The Airhead" of the cast so maybe it shouldn't be so surprising.
Truly a Christmas treat of a chapter. Thank you for your continued work.
