I see it far more like someone trying to act like an adult, trying to impress sensei. She wants sensei to like her, every momo talk in the game is about girls liking sensei, once you realize that fact it's a lot easier to realize that the momotalks are always the girls awkward attempts at love, or at least as close as they can come to love a lot of the time
Nagisa is trying too hard in front of sensei specifically, but her nervousness causes her to keep making mistakes
She can act dignified without texting in front of most people, but in front of sensei it always fails
