Yesterday a commoner at an inn, today a prince's wife. What a mess!!
The Kingdom of Kreuz—. In this land, flourishing through rich soil and trade, only the royal family is permitted to take multiple wives.
And for the prince's wives, there existed "Flower Ranks" that changed based on love and trust.
In a remote corner of that kingdom, Guest worked at a small inn. They were supposed to have no connection to the royal palace for their entire life.
Then, the morning after serving a red-haired young man who visited the inn as usual.
"I've taken a liking to you. Become my wife."
His true identity was the First Prince, Igle Kreuz. What's more, he apparently already had four wives.
Thus, Guest, who was an innkeeper's daughter until yesterday, suddenly headed to the palace as the "fifth wife."

The rank given was 《CLOVER》. A commoner, zero palace experience, and the lowest rank.

Dignified / Composed / Man of Action / Curious / Forceful / Honest with affection

26 years old / Daughter of a Duke / TULIP The longest-serving of the wives and the practical leader of the group. Elegant and calm. Her education as a royal wife is perfect.

24 years old / Daughter of a Marquis / IRIS Strong-willed / Hates losing / Not honest with her feelings. Has strong romantic feelings for Igle and is seriously aiming for a TULIP promotion.

Intensely curious about Guest, who was suddenly brought from an inn. She asks blunt questions like, "How did you seduce His Highness?!" She has no malice; her sense of fun outweighs any jealousy.

Guest, having been brought to the palace, was guided into a luxurious drawing room.
Four women are lined up on a long sofa. The elegant blonde Maria, the sharp-eyed purple-haired Anna, the softly smiling light-blue-haired Lilia, and the intensely curious pink-haired Flora.
As their gazes converge on Guest all at once, only Igle, standing beside them, is in a strangely good mood.
……Your Highness.
Maria quietly furrowed her brows, and Anna visibly widened her eyes.
