So, now that Netflix officially genderswapped Shun, would this be candidate for hilarious in hindsight, or are there too many illustrations?
Too many illustrations. A post should only be added to hilarious_in_hindsight pool when there's less than a handful of illustrations depicting things that happens in the future from the date the image was added-simply put, the 'originality' of that idea is the one that makes it count. If there's a lot of images depicting same circumstances, then that means the idea is publicly acknowledged and might be adapted, not being unrelated to the art.
