The Coronation of The Fifth Hades
It was not an easy ride; they meant the hunt. But somehow, Yuki and Damien managed to find the journal earlier than they assumed, thanks to this genius duchess. And the duke felt thoroughly emasculated because he dozed at the last minute but somewhat in awe of his wife, who cracked his father's complicated code. If not because of Yuki, Damien might take a longer time to look for the book, or maybe he would not find it at all.
That night, at last, the husband and wife could sleep in real peace after three weeks of hunting the Warlock's journal. Thank you, God! Oh, and yes. Since they began the search, the couple shared one room every night in the King's Palace. It happened because Damien, although it was his idea for two separated bedrooms, suddenly said it would be such a hassle for Yuki to return to the Queen's palace late at midnight and suggested they should share a bedchamber together.
