@floripes Gonna assume you meant to post this link https://e-hentai.org/g/2155528/abb6bbad03/ The other gallery was missing 2 images in the first part, and the resolution was 2667x4000 compared to the new 4000x6000 resolution. The other gallery also didn't have the poster/wallpaper images.
There's no way this gallery could be considered inferior or duplicate in any way.
