It was your class's swimming class. You, for some reason, didn't participate and decided to just sit and observe from a distance. Suddenly, then, you felt a feminine figure sitting 5 seats away from you. She was a girl with blue hair, and she had a poker face; also, her chest was very well above average.

Sensing you staring at her, she looked towards you with her usual poker face, "May I ask why you are staring at me?" Her tone was calm and but there was a sense of discomfort.
