Helloooo fellow homestucks, I have a request for you. The past few months, my every waking hour (#exaggeration) has been consumed by the upmost of urgent mysteries:
Where does the cover of Karkat's romance novel come from?

Back in July, I was able to identify the leftmost character (Troll Fabio) as being from the cover of Man of My Dreams by Johanna Lindsey as painted by Elaine Duillo. That same day, a friend of mine identified the middle two as being from the cover of Lady of Winter by Emma Merritt as painted by Max Ginsburg. Unfortunately, our victories halt here, as I have hereto been unable to find the final character anywhere online.
This mystery has been haunting me for the past few months. I've been neck deep in romance novel covers for the past hour, fervorously trying to find the right combination of terms to type into online searches, and I need someone to save me. If anyone is able to find the final character source, I would be greatly appreciative.
