While the panels of Kurokawa screaming looked goofy af, i feel like they conveyed the severity of her self-image quite well. Next chapter is going to get interesting, we either going to go the misinterpretation route where Kurokawa's words would make Nanaki feel like she regrets ever knowing her and its going to cause a rift between them and probably would need outside interference from all the friends. Or we get a decisive Nanaki snapping Kurokawa out of her manic episode and try to get some sense into her and tell her that the reason she's telling her she loves her its because she sees as her equal, but unless this manga is ending in like the next 3 chapters, i doubt we'll get that.
Also, Kurokawa's self-loathe kinda reminded me of Suoh from Flowers a bit since they both are seen as attractive by other people, but their dark past memories makes them feel not worthy of admiration from their peers.
