Looking at it from a subjective point of view the story itself isn’t a complete breathe taker or anything like that. However, it is worth the read especially for the characters themselves. There wasn’t a side character in this manhwa that I didn’t like, I absolutely adore the duchess and her husband and of course cute MLs are so much better than the alternative if I’m being honest! As for villains, Medea is definitely more interesting than your typical villains but the smaller ones like Leslies father and sister are just plain bad and not in a good way.
