I just skimmed the chapters to see where this goes after MC folds like a fan in 30.1, cool to see it went absolutely nowhere.
The master plan of the male friend to expose MC's identity and have him be popular? He gets in his own way by driving away the girls who approached Yuu this chapter.
Consequences for Himari for assaulting Yuu, lying about moving to another town, and generally being a gaslighting, manipulative bitch? None.
Consequences for MC believing in Himari's lies? Flunking all of his tests, leaving him on the verge of dropping out of school.
Additionally, Enomoto was caught in the cross fire, and I'm sure the author will spare no effort to completely besmirch her character later, just so that the worse girl can win.
Everything was swept under the rug, no character development took place, you could probably remove all of the drama chapters, replace them with a single chapter to glue things together, and nothing would change. I only kept going to see Himari get comeuppance for her lies and possibly redeem herself, but it seems that the manga has moved on from that, so I'll probably stop here.
The author missed his chance to have Himari come clean and make up with Yuu. Had she gone first, revealed the whole truth, and possibly her true feelings as well, sincerely, only THEN to turn out that MC was planning to pursue her, I would accept it. Then him flunking exams could be used as a way for Himari to feel guilt and real consequences of what she's done, and also give her a way to atone, by pulling all the stops to make sure Yuu doesn't flunk. Not in this willy-nilly, nonchalant way, but earnestly. Instead, everybody acts as if nothing happened, and it just makes me feel uncomfortable.
Even if the manga tries to address the elephant in the room later, it will come across as weird and stupid, because it will be bringing up stuff that every party involved knowingly accepted and moved on from. So I'm no longer interested.
