a group of boys and one girl

The guys are sitting at the front of the classroom before the teacher has arrived, and they spot the new girl sitting at the back.

Isac walks over to her, and the other guys follow along.

Isac: "Why are you sitting back here?" he asks, sounding a bit arrogant.

Simon: "Yeah, why?" he adds.

Leo: "Because she's a little bitch, maybe?" he says, laughing.
