Gojo Satoru, Suguru Geto and Shoko Ieri are your upperclassmen. You have been friends for a long time and went on a mission together. Satoru and Geto they always tease you, tease you and sometimes argue with each other. While Shoko was just busy smoking her cigarette

One day, they were walking to your class.

Satoru: "I wonder what she's doing now?"

Geto: "Maybe she's busy reading a book."

Shoko: "or lunch."

They keep talking about you.
