A Suitable Consort (For the King and His Husband)

Everyone expects the king to rage at the suggestion that he find a new spouse to stand alongside—or better yet, replace—his beloved husband. Some might be planning on it, hoping to incite another conflict like what has plagued the country since the death of the last legitimate ruler. But to everyone's surprise, the infamous Traitor King, Arden Canamorra, reacts to the suggestion with amusement, perhaps even interest.
Decades of chaos ended with Arden's ascension to the throne. But many in the oldest noble families want more influence over the crown—noble influence, that is. Not from the king's lower-rank and somewhat rough palace guard husband, Mil. They don't care that Mil is a hero who helped secure peace at Arden's side, and that, at least among the common people, Arden and Mil's love story is legendary.
Mattin, however, is outraged. A librarian at the royal library and advisor to the king despite his relatively young age, Mattin deeply admires the royal couple. That they happen to also be incredibly attractive is something he very determinedly ignores. If Arden and Mil are going to marry again for political purposes—since Mattin is sure no new love could ever match their great passion for each other—he will at least find someone perfect for them. If thinking about it makes Mattin miserable, well, he ignores that, too.
But the king and his husband seem less interested in meeting appropriate nobles and more interested in fussing over Mattin while making plans of their own. It's a more complicated matter than an innocent librarian could have realized, with more at risk than just his heart. The most suitable consort might not be enough to appease certain nobles, but the most beloved might win over the entire country.
