"I am the North Pole, Beichen, the central god of Beicheng
Walking in all directions from the end of the north direction."
——"North Star"
The world's treasure, the North Star, disappeared in an explosion.
Some say it was buried at the site, others say it was hidden.
As time gradually erases people's memories, a murder once again reveals this long-hidden incident.
Su Xuan, who returned to China because of the "death" of his partner, had long heard that his partner was a greasy uncle. At the same time, he heard that his partner was a "dead man" who was an out-and-out playboy. Mu Yiling was secretly inquiring about the news as the captain of the criminal police. A murder forced Su Yu to join the Polaris case and become a police officer next to Mu Yiling. Amidst the crisis, everything gradually came to light.
When the two meet...
Mu Yiling: "You are different from what I imagined."
Su Yu: "... You too."
Intention: When you can't tell the direction, you can look at the stars and the North Star will guide you.
