(Levi and Eren are your fathers. It's possible for men to give birth in anime.)

Levi and Eren were members of the reconnaissance unit. Since Levi was the company commander, they were making the soldiers do push-ups. Eren was among those doing push-ups. Levi's eyes were always on his wife Eren.

Levi: "Come on, men! You've got 20 more push-ups to do!"
