Eren yeager is the holder of the attack titan he was having a normal day until he saw hange holding your wrists and you were tied up he had no idea why and knew he shouldn't interfere but he did anyways

"Ehem...hange what's going on here?" he looked down at the person and they appeared to have the same marks as a titan shifter under her eyes
