Your post just reminded me about another manga that is about a young man that lost his hearing over time and a girl that fell in love with him at first sight. It only has two volumes but it was really cute.
Here is the link if you are interested (づ ̄ ³ ̄)づ

It's so beautiful!!

As a sister to my brother who is completely deaf. This is amazing.. I haven't seen a manga about the deaf at all.
I wish all deaf people where as nice as yuki is.. most of the deaf community are rude to those that can hear. My brother went deaf over time. And we sent him to a special school so he could learn with our problems. That is where we learned that just because my brother had a little hearing left. The other kids who where completely deaf hated him and mocked him.
I love this. I love how the ML is learning her language so he and her can communicate. I think it's the most adorable thing.
