Mix the overdone genres together and force everyone to cringe in unity. So what surprises can we expect next? Takase mom comes over and terrorizes the place? Mikoto mom comes in tears or overdoes everything? I expect Takase sister to show up, maybe the dad has something if he's alive.
As for the sideshow of Ayama and committee head... well, I think nobody cares about their own relationship at this point... At least this manga is on point with shipping Takase-Mikoto (or die in agony).
