Isso Koe ga Nakattara
Kakeru, working as a janitor, stutters a lot and hence doesn't have any friends. He then meets takashino, an employee in the same company, to give something he dropped but then he gets rlly shy and hence runs crying. It's rlly cute how they spend time and eventually clear obstacles Sex is not extreme but not soffttttt also, I prefer this story more than sex in this one so read under caution
Kikoeru?
The shy uke listens to a radio dj from middle school and one day suddenly meets him in a book store and with all his courage talks to him. He Thn starts meeting the dj frequently and consults his problem with meeting strangers, so with the encouragement from dj he starts to associate with others. Eventually they fall in love but never tell each other and stops meeting Sex is shown only in last two chapters and it's rlly good
