A political marriage pairs a timid “rabbit” with the North’s feared “black wolf”—who turns out to be a small, anxious pup of a duke. Through patient care, the fragile husband finds confidence, only to be drafted and vanish in war. Years later, the groom presumed dead returns as a formidable wolf, upending the quiet life of a would-be nun and reigniting a bond that never faded. This is a slow-burn reunion romance about healing, devotion, and learning what “adult love” means when the heart still remembers the gentle pup inside.
