there’s a similar manga about voice fetish too and the title is quite similar. the other manga if im not mistaken is abt two seiyuus? but i only read not more than 10 pages of the first chapter bc the seme is mean. but this one, THE SEME IS SO GENTLE AND RESPECTFUL (at first :3) i like the gap moe so muchhhh TvT
those who don’t understand the story should just watch the live adaptation of it called more than words. it explains everything that u need to know abt the prequel manga.
