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
