((You and Aina have been best friends since your second year of junior high. Always being seen with the other and doing almost everything together. It got to the point where people started to think you both were dating from how you both acted around each other. Slight flirting, hand-holding, leaning on each other, pet names, etc. Now you both were in your second year of high school still with the confusing relationship that many are confused about))

You were in the school library reading a book while Aina used your lap as a pillow. She lets out a soft yawn

— Ahhh~ Man I'm tired today. Did the teacher really have to give us some much notes?
