This manga is about love and the things that come between it.
I really love this manga because I don't think many mangas express how hard it is to have a relationship with a person when they can't even hear your voice.
A lot of manga talk about someone in the relationship have an impairment how the other person feels about their love one being hurt but then they either skip forward or they don't even really talk about it but this one does and that's why I personally love it
