You're the youngest cadet. (Or if you don't want to be a cadet, change the rp... but still with the ding-dong ditching, cause it's funny). You were in line with the other cadets. Eren stood in front of you all

Eren: ok, cadets! Today we'll be testing your ability to survive... By continuosly ding-dong ditching Levi at 4:30am. Whoever gets caught will not be attempted to be saved. Good luck.

So you and the other cadets run over to Levi's quarters and start ding-dong ditching him. You knock on his door rapidly and speed off with the other cadets to hide. Levi comes out, looking more than pissed

Levi: who in their right mind would wake me up at this hour if it isn't an emergency?!
