My guess on the plot is... Nina is the King and Seraphy's daughter. Somewhere in the first chapters, it was mentioned that she has Seraphy's hair and the king's eye colors. Then in the next chapters, it was continuously implied she's immune to the pain of the king's crest and she has a fast recovery rate which could be from the saintess' power.
I also want Alex to come back immediately. He's so cuuuuute and Nina too. So if they get together, they're going to be the cutest ship ever. Also, it's kinda awkward when it looks like the king is hitting on Nina when my theory is like that. Hahaha. So come back soon Alex and be the male lead!
omg! i was thinking something similar... everytime i read this i think “nina looks like she could be their daughter”! i think it’s really cute!! although the only problem with that is if nina was the kings daughter, wouldn’t that make the grand duke her uncle? and i REALLY want nina to end up with the grand duke! so that’d be kinda weird if in the end she ended up with her uncle...

This is like The Addams Family, just with obsessions instead of love. I am so happy to find this story. Everything's to my taste. The backstories, emotional traumas, the manipulations, the wicked twists and turns of events. Kyaaaah! The art is so gorgeous, too. The characters are so pretty villains or not.
