Sissi, commander of a regiment in the Arlemania Army, is admired by many of her subordinates. But she feels a peculiar distance with her direct subordinate, Cecil — though he has excellent looks, family background, and military skill, he’s cold and unapproachable toward only her. One mission later, Cecil’s entire attitude toward Sissi changes drastically—turning into relentless attention. A romance starts between a cool senior female commander and her younger, exceptionally capable subordinate whose feelings have been turmoil‑building in secret.
