This is the peaceful small country of Bramble Kingdom.
But one day, I realized that I was being targeted by a great power ...-

"You are the queen of this country."
-You were suddenly selected as a queen.
Its only mission is ato have a "contract marriage" to protect the country ...!?

The encounter and love of 11 of them from five countries will lead to their destiny.

"Swear with this kiss ... you're the only queen of me."　
When the crown shines above you, the lie turns into a true kiss.
