Attack on Titan: Levi's Regrets (fan-fiction novel)

ATTENTION: These characters are not mine! They're from the series Attack on Titan created by Hajime Isayama. This story is the novel version of my recently made fan-fanfic comic. (The pictures don't belong to me) It takes place after the 57th expedition, and it focuses on Levi's regrets towards his squad's death especially Petra's, and how it surfaces memories of what Levi wants to drown. As Levi tries to move forward there comes a shocking event that gives Levi the second chance he dreamed for. (As you can tell this is a 'Levi x Petra' fan-fiction). Warning: if you read the manga, try to forget most of the events that happened after the 3rd season in the anime series which takes place in the anime more than the manga and that this story will travel down a slightly different path. What can I say it's a fanfic. Also check out the comic version if you're interested for more visuals.
