In this article, we've collected some representative illustrations featuring girls in the #ふつくしい tag. Check them out, but don't forget to keep breathing! In and out, my friend, in and out.
On pixiv, when an illustration is so lovely that it takes your breath away, it gets tagged #ふつくしい (futsukushii). This is a tag that's been around on pixiv for a long time, probably because it hits home for a lot of people!
