To be fair, is gettin kinda boring with kuzumi not communicatin at all, it aint even that he doesnt talk, he just wont try to communicate, and dont give me that "there's people out there like that" is just gettin boring, Komi-san ie. she really tries to talk and does communicate to people by writing, she is trying and she is doing it.
But im really looking forward for the Yukko x Haruna development
Edit: And know that i think about it, with the long break this manga took, picking this manga up again made me realize how lame kuzumi is and how boring it turned out to be after they started goin out, like before it was just the erika-side of the story so it didnt even matter that he was so muted all the time, but now, jesus
