I actually didn't know this was a thing before the anime came out, and even then I wasn't that interested in the anime, but it then got big on Tumblr and stuff and I'm like: "UGH FINE" and watched it. Omf. So happy I did. I rarely follow a manga after the anime, but this got me hooked so bad I just had to continue to see what happened. I also wanted to see more of my adorable Levi. <3 -fangirling-
