Humanities Strongest

An AOT fanfic
hello, many years ago I used to use this app to make many fanfics specifically one of my favourite characters Levi X readers, I came back to this app recently to write a werewolf novel which you can find in my works Snow White and Her Alpha while doing so I was curious of my old work and read through them, I was surprised how much people enjoyed them back then and so thought I should try to redo one but make it better since I believe I have come a long way as a writer, I shall be making two of these, one being this based of the actual anime, and the second being a modern novel like the story just with the AOT characters however, this will not be one of my old Levi x Readers I will add a new oc and still I hope you enjoy and give me feedback now on with the desc.

what happens when the Humanities strongest meets someone who can hold their own against him, someone he can not understand and who challenges him more than ever? someone he comes to loath but at the same time wish to always be near them?
