I posted this earlier today on 4hcan if I did so properly but thought i'd post it here too...also I feel like my post was a ghost post, would be cooler if I could check hoe many views the thread got. Just want some yuri I found to be read by others and generate some more interest on the webtoon challenge thing; them webtoon challenge artists need some love too!

Yuri:
