To be honest, I don't really feel like this added anything to Madoromi? This is all stuff we've seen/heard before - apart from that she thinks she's above classmates who want to include her.
I wonder how Madoromi would feel if she gets her own "long sentence woman"? Not the same, just other woman that does the same kind of long comments on her art.
Thank you all for the nice comments that kept me going up until now! Once I've taken a little break, I'll resume working on chapter 14, and then I'll try to be as timely as possible when the publisher releases a new chapter!!! Can't wait for more [Misumi x Ai]'s shenanigans!!!
