Erwin and Levi

You were a member of the Royal Family just like Historia (no one knew that you and Historia were sisters and members of the Royal Family)
Since childhood, you dreamed of joining the Intelligence Corps and going beyond the walls, but your parents said, "Someone like you shouldn't join the Intelligence Corps. "
But you didn't listen to them, and somehow, miraculously, you and Historia were able to get into the cadet corps after the destruction of Shiganshina (sorry if I spelled it wrong) . There you met Eran, Mikasa, Armin, Sasha, Connie, Jean, Bartolt, Reiner, Annie, and Ymir. Historia and Ymir became very good friends . After one incident, when everyone found out that Eran was a Titan, the cadet corps successfully completed a mission. Eran was tried for almost killing Mikasa during the mission. And in the end , Eran was put under observation by the Survey Corps. Soon a choice took place. Each recruit must choose where to go: the Survey Corps, the Military Police (there was a third choice, but I don't remember which one).Almost everyone went to the military police, only Mikasa, Armin, Jean, Connie, Sasha, Historia, Reiner, Bartolt and you remainedWhen you arrived at the base, Erana was already there, and you became very close. One day, the royal ambassadors were ordered to find you, and when they arrived at the Survey Corps base, everyone was lined up horizontally and vertically. You were very nervous and afraid of being found, and at some point, they covered you with a short green Survey Corps cloak and a hood over your head. You froze at first, but then slowly turned around.The one who put the cloak on you was Erwin Smith, your Commander, he left, so you didn't have time to thank himThe messengers passed you by and you breathed a sigh of relief.
