Spoilers:
In the novel, the queen does this ritual and uses Enzo's life in exchange. He dies in Freya's arms (she is falling for him) and Ruby is sent to Romagna to become Caezar prisoner. He poisoned the pope and killed Enzo so he could be the new pope and be with Ruby.
Iske takes the dragon and goes rescue her. I don't remember a lot after this, but all ends well hahahaha
Honestly, they didn't explore a lot the relationship between Enzo and Freya in the webtoon, so I think this part could change.
Thank you
I hope they go with a change and Enzo will get to live
Okay so I desperately need spoilers
What’s going to happen to ruby now???
