I haven’t watched either of these, but if this kind of story interests you, then there are two manga recommendations I can make.

• You Talk Too Much, So Just Shut It Already! - A cute romance story set in high school in which the female lead is deaf. The scanlators have gone above and beyond with many of the chapters by creating gifs and explaining aspects of Japanese Sign Language that are depicted in the series.
• Love’s in Sight! - Alright, this one isn’t about deafness, but blindness. Another romance set in school in which the female lead attends a school for the blind and the male lead has normal vision. This manga has finished publication and is excellent, highly recommended. It does a great job of depicting the finer points of different types of vision impairment through the FMC and her fellow schoolmates.
