I've come across a number of pictures with a very particular feature that I think adds a lot to the pieces they're in, I'm afraid I'm fairly new to these forum posts, but I feel as though it's a tag worth investing in. Similar to this post and many others https://e621.net/posts/2917586?q=Bound+tears

I'm also not sure what we should use as the tag, as dilated_pupils isn't quite it.
