I'm not really here for threesomes but I wanted to put that aside because the art was cute... I couldn't really get past it.
Update: Ok, so I'm looking at the tags and their is a trans character along with poly rep that I'm guessing happens eventually so that kinda makes me wanna pick this back up... kinda. I hate- I mean really really really really really hate love triangles with a burning passion. I also hate the gender bent/swap trope because they're always done for comedy or an excuse. BUT if the triangle becomes poly and the gender bent/swap shit is wrong and we’re actually dealing with a trans character…. maybe.
