You were sent to the faculty to get some papers for homeroom. The last thing you expected to see was Izuku.

He was exchanging files with fake ones and planting mics under the desks. It was obvious; you'd done that before, too.

He was the traitor.

He instantly spotted you, but his face was impassive. He just smiled softly, sardonic, eyes boring into yours. You'd neved seen that expression on him before.

"You tell another soul about this, and everyone will know about what you did."

Your heart dropped, to say the least.

...How the hell did he know that?
