@Alibekeee There's not much of an explanation, but it was in the first set of chapters: Tadano caught Komi meowing to herself at her cat trinket, and that's what sparked Tadano figuring out she was really bad at speaking with others. When he recommended writing on the board instead of talking...
So anyway, what're people hoping for from the next few chapters? I know "more Komi/Tadano development" will probably be a popular answer, so let's avoid the obvious.
I wouldn't mind more Shosuke and Hitomi antics, personally.
@ShinitaiKoroshitekure Hey man, we're not attacking you for liking stuff like Jojo's, DN, or YuruYuri. Just let us enjoy our quirky little SoL in peace.
