Last chapter could have been a huge moment of self reflection for Megumi on how blisteringly inconsiderate she is of Aoki but all she got from that whole moment was "I gotta see how big of a slut my secret boyfriend I won't admit to dating is."
But everything is allllll better because she squashed some anime titties on his back extra hard so phew, dodged that bullet where she could've learned something, everything's hunky dory!
Real old reply, but let me remind you that she pockets only 2 months of love-relationship experience. Even Kuroki is astonished to the her childlike innocence when it comes to being in love.
Megumi admitted the possible scenario where Hanazawa might have actually sprained her ankle, though she does bounce back to lending shoulder argument. But is she in the wrong to be jealous? After all, shouldn't a couple be jealous if their partner goes close with other's potential rival?
Not like being adult makes you very wise and very forgiving towards it, no. Heck, they even handled it well, here.
