Sorry not a real answer but, I would recommend you trying some fanfiction as well. There are some pretty good Erwin/Levi stories out there. Only if you're interested tho. You could try sites like ao3, etc. Anyway good luck to you, wish you luck <3
is there a bl manga/manhwa that has a similar trope to erwin and levi's ackerbond? (from aot)
