Interclass Event [4]

"Hello, sis. Been a while since we talked, hasn't it?" I said as I put my plate on the table and sat before the girl.

The girl had long blonde hair and leaf-like green eyes. She was none other than my older sister, Anya.

"Huh? Ah, Zero…it's you," she broke the silence and said as if surprised by my sudden appearance.

"Well, should I not be here?" I asked though I know this question had a fixed answer.

"No, it isn't like that. I was just…not expecting you this time," she clarified.

That exchange was it, silence prevailed between us after that; I started munching on my sandwiches while she sipped her drink—what looked like green tea by the way.

As Anya drank her tea, she kept looking outside through the glass panes, she was not much aware of her surroundings and was acting different from her usual behavior; it was as if she was lost in her own world.
