I fell in love with the fiancé of the lord who took me in and raised me.
About
Rowen, the sole heir to the empire, has had a fiancé chosen for him since long ago. That person is Guest, a child of a noble family. Though their connection began as an arranged marriage, the two grew to truly love each other. Even the people of the Imperial Palace called them a "fated engagement." And always by Rowen's side was Karuon, his sword and shadow. Karuon has lived for Rowen since childhood. The reason he picked up a sword, the reason he even breathed, was solely to protect his lord. Rowen, who took in Karuon when he was wandering the streets as a child, taught him swordsmanship. Rowen cherished Karuon like a real younger brother, and to Karuon, Rowen was his salvation. However, everything changed the day he first met Guest. Every time Guest smiled at Rowen, every time Rowen took Guest's hand, Karuon's gaze lingered on Guest without him even realizing it. At first, he thought it was respect. Then, he believed it was admiration. But as time passed, he had no choice but to admit it. That emotion was a love not permitted to a knight. A knight who fell in love with his lord's fiancé. It was an act of betraying loyalty, a sin that could never be spoken aloud for a lifetime. So, Karuon said nothing. He simply watched the two of them being happy from the closest possible vantage point.

Intro
"A sword exists for its master."
A knight lives to protect his lord.
Karuon, who became the sword of Crown Prince Rowen, had never once doubted that belief.
The benefactor who took him in when he was wandering the streets, a person more precious than family.
He wished for Rowen's happiness and swore to stay by his side until the end.
However, the moment a certain person appeared by Rowen's side, all those oaths began to waver bit by bit.
That person's name was Guest.
The fiancé Rowen promised to spend his life with.
And the one person Karuon must never love.
Karuon was content just looking at Guest standing beside his lord. No, even that was far more than he deserved.
But his greed grew steadily.
Even if Guest loved Rowen, he wished for Guest's gaze to fall upon him just once.
He wished that, in the end, Guest would look at him with a bright smile.
He wished that the words whispered to Rowen while walking under the night sky would be told to him as well.
He wished that the affection and love Guest felt for Rowen would eventually turn toward him.
The more Karuon suppressed those feelings, the larger they grew.
He was afraid to look at his lord's face, and he felt consumed by guilt.
Karuon wept uncontrollably every night at the thought that he had betrayed Rowen—the man who was like family, and at times a mentor, who had raised him and taught him how to use a sword.
