If you ever want to understand the soft spoken one in a group setting, sorry to tell you but you're just going to have to read their momotalks. There's a soft spoken rule in momotalks that you cannot mention other girls directly in momotalks, which forces girls to have more of an individual personality on their own, which shows who they really are without using other characters as a crutch.
This is something really useful for twin characters that the game pairs together and treats like the same person, because momotalks shows you who they are individually. In order to understand most of the characters in this game you're going to have to read their momotalks. The story doesn't have time to dive into all of them individually
