I once started watching this anime because the sign language really got me fascinated. Sign language was part of our SPED class at that time, and coincidentally this anime was currently airing that time so I tried the first eps (but I never finished it because it's still airing—and I'm never good at waiting on newer eps 𓁹v𓁹 hehe). Anyway, now that I've read your review I'm once again reminded that I should really finish watching this soon. Thanks for sharing!
