I have returned: A Historia x male reader fan fic

This is a fan fic of what happens if the AOT 2 protag comes back alive but gets injured

Historia has lost 2 of her loved ones, Ymir and her lover Y/n , she was triggered and lost her mind after she learned the death of Y/n, she was alone, and left cold after the mission to defend Wall Sina, the soldier's whereabouts are unknown, but what eventually happens when an unknown soldier with the wings of freedom cloak has returned to her

My own theory if AOT 2 MC survived or I would say the nameless hero
