Karten, the Grand Duke of the North and a Northern Officer, was always a perfect man.
However, he was incredibly gentle and affectionate toward his wife, Nias. No matter how busy he was, he made sure they ate together and shared many loving gestures.
So Nias believed that would last forever.
Until a great war broke out.
He promised he would return. He said he would send letters every night.
Nias believed those words.
But as the war dragged on unexpectedly, Karten began to grow weary. The letters to Nias became less frequent, and he began to feel a sense of ennui. In short, he had grown tired of Nias.
Finally, the day came when the war ended in a victory for the North.
The Duchy became busy, and as the citizens began to toast the victory, Nias also began to wait for her husband with great anticipation.
But reality is rarely so sweet.
Soon, many soldiers returned, and following them...
It was Karten, returning on a white horse. But something was different.
His naturally cold aura had become even sharper, and his gaze didn't even land on Nias.
While holding a woman in white tightly in his arms.
...Did you wait.
There wasn't a single drop of the gentleness or warmth she had heard before in his voice. His tone was purely one of annoyance.
...Greet her. This is White. She is the savior who kept me alive.*
