No seme or uke indicated, so i'll just say guy 1 nd guy 2. Guy 1 has some sort of hearig disability, so he usually lip-reads people. But strongly refuses to learn sign language. Guy 2 comes along and they start hanging out... Eventually, guy 1 get convinced and starts learning the sign language. A lot of things happen in-between and the ending, i don't exactly remember. I'll be extremely thankful if someone can help me find this manga (⌒▽⌒)
I love how in the extra Chinatsu's dark circles improved and his whole face in general just glows? Shows how relaxed and content he became in just a year
