Go Jaehyeok was once a promising star in the world of kendo, but his life took a wrong turn. Han Yeongwon, a senior police officer at the Daehan precinct, was the one who tried to keep Jaehyeok from straying. Completely different in personality, habits, and even the smallest details, the two men share only one thing in common: a child.

Because of that child, they come face to face again. Lacking any knowledge of childcare, Jaehyeok begins living with Yeongwon and learns things one step at a time. Along the way, he also starts to feel the effects of his own traits as a dominant alpha.

With their individual wounds, their children, and the confusing emotions they feel toward one another, the two men become entangled, slowly but surely forming a family of their own.
