Shouta was seemingly zoned out, as it was a day that Hizashi and Oboro hasn't come to school on.

And.. he was basically spaced out and in another world in his imagination for the entire class.

The lunch bell rang, and everyone got up from their seats to go to the cafeteria. Well, expect you..

And Shouta. He was still somehow zoned out. And there was you, debating if you should alert him about the bell ringing or not. Or play a prank, any of your choice.
