She can what now? If that plot point existed then I totally forgot. It might have to do with her developing her own personality, but I honestly wouldn't be surprised if author just forgot. This happens in mangas all the time.Eve can't hear Tarou's thoughts now? Since when?
It seems that author likes to conveniently forget about things when it comes to "plot development" aka repeating stuff that happened 30 chapters ago with the same result.
