normally I don’t do one of these unless I have two doujin to present but holy fuck this one was good.
To Make Myself Mine by jouki

This one starts off a bit generic but actually is one of the VERY few doujin which explores Erwin and Levi’s last conversation, Erwin’s death, Levi’s handling of his body, and him coping in the immediate aftermath of his death. It was really really cute and it made me feel sick with how sad and bittersweet it was at the same time. They’re just so damn wholesome and smol.
Please be aware this one is in two parts (click to part 2 at the bottom of the page) and it does end up with actually a super happy ending I think! Pleeeeease check this one out- also @lostcauses-noregrets I think you’ll love this one.
