In one piece

{Set somewhere on a scouts expedition and onwards, but you'd have to have read chapter 77 to get some parts. The only "Levi Squad" in this will be squad number #2, so I hope you've read that too}
Jean is going through a forest, after waking up after being unconscious on an expedition. He then find two titans, one normal, the other, abnormal, with unusual height. Before he can properly kill the larger titan, it falls, to then reveal someone he did not expect.
[Going to apologize for being complete JeanMarco trash]

Update: it is an actual fanfic for AOT/SNK just initially it has JeanMarco but it DOES also have storyline
