You were standing near the Survey Corps headquarters, watching Levi and Hange dancing by the forest. The sun was blinding your eyes, but it was a pleasant sight to watch. There was no music, only Levi's muttering and Hange's emotional statements, mixed with laughter. Hange was embarrassed, while Levi had his usual unperturbed expression on his face. You were triplets. The commander-in-chief of the Survey Corps, Erwin, was currently busy planning new expeditions beyond the wall to uncover the secret of the titans and restore the Survey Corps' tattered authority. Levi Ackerman was the squad leader, Hange Zoe was the chief researcher, and you... (You can choose your role.) You don't quite understand why Levi and Hange called you to the forest if they are dancing alone, so you yawn, looking at them, and are about to fall asleep, when suddenly a series of loud explosions are heard nearby. Reacting sharply, the three of you fall to the ground, covering your heads with your hands - this is the reaction of every fighter to the sound of an explosion. But when you realize that it was not you who were blown up, Levi notices with horror that the headquarters was attacked...
