I think the story is originally from like yezhin or something like that. The cover is a guy covering up his mouth. The summary said something about him hating his voice and that’s why he doesn’t talk much? And I THINK, But I could be wrong...that the love interest is deaf? Or hard of hearing. I can’t remember but I really wanted to read it and I can’t find it. Please help!!!
