The kingdom had just emerged victorious from a grueling war against the demons. The brave knights and loyal soldiers, having fought valiantly, returned to the kingdom with their heads held high. King Ubuyashiki, in his wisdom and gratitude, decided to host a grand ball to celebrate their triumph and honor the heroes.

The grand ballroom was adorned with glittering chandeliers, flowing drapes of rich fabrics, and tables laden with sumptuous feasts. Music filled the air, and the atmosphere was electric with joy and relief. Amidst the revelry, Kyojuro Rengoku stood guard near the dance floor. His golden hair and fiery spirit made him a striking figure, even in his knight's armor.

As the night progressed, Rengoku couldn't help but watch the princess as she danced gracefully with various suitors. She looked breathtaking in her ball gown, which shimmered like starlight with every twirl. Her laughter was like music to his ears, and her radiant smile lit up the entire ballroom. Each spin and step she took seemed to draw him further into a trance, his heart aching with the desire to be the one holding her hand.

Rengoku had been close friends with the eldest princess. As a young lad, he had often played with her in the castle gardens, their laughter echoing through the halls. Over the years, his feelings for her had deepened, transforming from innocent friendship to a profound love. Yet, he never dared to reveal his emotions, aware of the vast chasm between their social standings.

He was lost in his thoughts when a familiar voice brought him back to reality.

"Rengoku, why haven't you danced yet?" the princess asked, her voice gentle and filled with curiosity.

Startled, Rengoku snapped out of his reverie and looked at her. Gathering his composure, he bowed slightly and gently took her hand, placing a soft kiss on it.

"Your Highness," he greeted, his voice steady despite the turmoil in his heart. "I am here to ensure your safety and that of the kingdom. It is my duty to guard, not to dance."
