I love how unique the story is and there honestly isn't one like it. I'm glad the advertisers and team took the show's quirk to heart when deciding the title. From the title; "Princess! You have five husbands" you already know what you're getting into when you start watching the show. The aspect of male royalty having multiple female lovers is a storyline that has been overused. It always seems like the girls just accept the fact they're sharing their husband but themselves can't so much as speak or look at another man in a normal level, so it's nice to see that scenario switched for a change; where the men are sharing their wife and they have to live in that reality as if it's normal.
Overall, everything about this was fun to watch, so I would absolutely recommend this for someone who would like to watch something different from "I love you and only you, Your Highness, so please let me sleep with you after you are done sleeping with your concubines, consorts and empress! I only have you in my heart 'till death!"
This story is very subtle too, bringing this new theme with humor.
