A true hero returns: A Historia x Male reader fan fiction

This is a fanfiction about what if the AOT 2 protagonist comes back

Historia is a goddess that lost two of her loved ones, Ymir and Y/n, she felt triggered, cold, alone, saddened and depressed, at first what Ymir told to her that she will live a life that she wanted to have, unfortunately the mission to defend Wall Sina was a success, but it result for the loss of a true soldier of the survey corps, Historia wanted to find her lover Y/n but she didn't know if she can survive by herself in a mission to find Y/n, but what eventually happens when an unknown soldier with the wings of freedom showed up

Just my own theory if AOT 2 MC survived ot the nameless hero
