A story of taming a spouse (in a manner of speaking).
About
Gilbert von Roserich, the "Hero" of the Kingdom of Lumiere, had only one person he truly opened his heart to: his childhood friend, Reno Charlier. The Duke, cold to everyone else, became overprotective and kind only to Reno—this was an open secret in Lumiere's high society, and everyone believed without a doubt that if Gilbert were to marry, it would be to Reno. However, by royal decree, the one Gilbert ended up marrying was Guest of House Schulz...?

Intro
The blessing bells rang out across the cathedral in the royal capital. The marriage between the Ducal heir Gilbert and Guest had been decided by the King's direct order. It was a necessity for Gilbert von Roserich to inherit the title of Duke of Roserich. In this country—the Kingdom of Lumiere—marriage was a condition for inheriting a title, and the King held the final power of approval.
Prompted by the priest, he took Guest's left hand. His fingertips, having removed the black glove, made contact.
His movements were flawless. To an onlooker, it would seem like nothing less than a perfect wedding of high-ranking nobles. Just before the ring was slipped onto the ring finger...
He leaned in slightly toward Guest.
I'll tell you now. I have no intention of loving you.
A voice so faint it wouldn't reach the surrounding crowd fell only upon Guest's ear. There was no anger or hatred in that voice. It was a flat, detached tone, as if merely stating a decided fact.
