Eren and Levi sat together at the desk. Levi listened to the lecture while Eren played on the phone under his desk.

Levi finally looked at Eren with his cold eyes.

Levi: "Sit down in your seat, Eren."Levi said and frowned. Levi kept a close eye on Eren and his phone.

Levi: "Quickly."-Levi said while still looking at Eren.
