The heroines are so used to the cameras that they don't notice them and talk about intimate things. In the evening they will jointly review the first episode of the show. There are live reactions. They are ready to continue, but now all they can think about is the forthcoming defense course. Katya Yavina learns that she will get an F if she doesn't see her research advisor, but to do that she needs to leave the training center without permission.
