The girl watched Eren leaving the room. Seeing how easily he agreed to go, she felt a surge of frustration.
How could he be so nonchalant when a girl like her was leaving him? She simply couldn't understand his indifferent behavior.
However, the moment Eren paused at the threshold, her thoughts began to calm down. Her gaze turned cold once more. She was convinced that Eren had only been pretending to be carefree before. He was surely going to beg her not to leave him.
There was no doubt in her mind that Eren did not want her to leave. Why else would he hesitate to exit the room? It was all starting to make sense to her.
Previously, his casual demeanor had been an act, a plot to see if she would stop him from leaving. And now that she hadn't intervened, he was going to reveal his true feelings and desperation for her to stay.
