This was one giant feel-good manga. I'll admit the first half was a little difficult for me to get into because while the subject is somewhat heavy and serious, I just wasn't really into the story or had much of an attachment to the characters (probably because this manga is also hella fluffy making it lack emotional weight). But as it progressed, I grew to really like it. The characters have such an organic and pure romantic development that it really makes you feel like you're going on this journey with them. But the one thing that really sold this to me was the concept/moral. I absolutely loved the issue they address about hearing impairment and how it is often overlooked because it is often deemed as not as big of an issue as complete deafness. Because of this common misconception, characters with this impairment not only have to work hard trying to get through everyday with difficulty, but also seem to have try harder adjusting themselves just to make it easier and more comfortable for everyone else to understand them.
This really hits home for me because I've been diagnosed, and am still struggling, with ADD since I was 8. And it's because of the common idea that "ADD/ADHD isn't a real thing" or that "everyone has trouble focusing" that I've spent much of life telling myself what I have isn't a "real problem." Of course I don't let having ADD completely define who I am, but like the one's in the manga who have hearing impairment, passing off one's physical or psychological impairment as being just an excuse or no big deal can really make the struggle even harder.
*Most definitely the best message/moral I've read in a shounen-ai/yaoi.
