Thanks for the Update Daphie! aahhh what a bliss to see them happy... And there's nothing Madoromi can do to stop it xD lo/ I was going to comment right away but I wanted to measure everyone's else impression of this character first, I knew it wasn't gonna be positive of course and you're all right, we know she has a nasty personality but this time around is like she couldn't take it anymore and the jealousy twisted her personality even worse.
When she was insulting Ai but she got ignored and Misumi and Ai went hand in hand into the attraction, that was gold! because for too long she has been getting away with being a jerk and that's the worse part, sure she can be as nasty and egocentric as she want but why the others have to just accept it? only this time around Misumi is reacting but not so much, just some "Hey!"
I would've doubled down, I would've wrote this chapter differently with Misumi getting actually mad with Madoromi for insulting over and over her girlfriend, to stop her once and for all ... And maybe then we could've avoided the scene in the bath that was creepy and desperate, and now we know that she's just used to get everything she wanted from her parents.
ON TOP OF ALL THAT she outed Misumi to the teacher!! MISUMI'S TEACHER! that's too many red flags
