I kinda figure this is another chapter where a Club President knows that Ueno likes Tanaka and wants her to admit it, especially since Soegi is the only girl we know has a boyfriend already
@xxii_ I doubt it, she seems to be abrasive as a defense mechanism: annoy people so they leave her alone and leave her in peace to read weird books. She's probably also a bit awkward around guys, that would explain her willingness to make sexual harassment accusations about nearly everything Tanaka does and says.
@Tamerlane Deaf people make as much noise as non-deaf people. I visited a school for the deaf once to help someone with their computer and was surprised at how loud the kids playing were. They're deaf, not mute.
@SafetyShark At this point I'm pretty sure all the female club presidents know Ueno likes Tanaka. I wouldn't be surprised if most of the school knows as well.
@manabi Hanamori didn't know in her guest chapter (although likely does now), and Nishikibe seems like she might not know if you look at the raw of Chapter 85 (I can't read it, so idk)
Since Ueno called her the biggest pervert in the school, I'm not sure if I can possibly imagine what she said. Tanaka would probably misunderstand even if he heard it due to his immeasurable level of denseness anyway.
