A miserable life where even dreams of love were out of reach. The night I tried to end my life from the exhaustion of my joyless marriage, a special invitation arrived unexpectedly. [ You are an existence that gleams like the jewels. The Jewel Box, where existences who shine like you gather... Would you like to enter the Jewel Box? YES? or NO? ] [ The Empire's Jewel Box ] is a luxurious party attended by only the most outstanding people. A place where they can meet a marriage partner solely based on "true love" while concealing their face and status. "If you were granted the opportunity to become a shining Jewel, like those who were specially selected..." My choice from that night changed everything.
