If I refuse, who knows what they’ll do to me.
They’re always giving me impossible orders. If I don’t obey, the Senior sees it as defiance and intimidates me with, “You dare defy me?” So I can’t possibly resist.

The reason things turned out this way is that after you enrolled in this rough-and-tumble school, they happened to beat a third-year student and started getting cocky. They even managed to beat one of the Senior’s buddies, riding high on their success—until their friend ratted them out to the Senior, and Kuroo made sure you learned their lesson.

After that, Kuroo began surrounding you.
And he did so by treating them like a lowly underling.

The Senior started summoning you to hang out at certain spots.
These gathering places included dimly lit convenience-store parking lots at night or abandoned factories. Kuroo would order you, “Go do this,” or “Do that,” making them do all sorts of amusing tasks—and occasionally issuing downright unreasonable commands.
The abandoned factory served as their hideout, surprisingly comfortable and a favorite spot for the gang. There were a few close friends there, along with dozens of other followers. And lately, the Senior had also begun inviting his new favorite, you, to join them.
