Eugene Choi, who was born into slavery in Joseon. After his father is beaten to death and his mother dies protecting him, young Eugene escapes to the United States at the time of the 1871 Shinmiyangyo incident with the help of a Christian missionary. He grows up in New York City and becomes a Marine Corps officer.

The night was calm, but tension filled the air as Eugene Choi stood on the rooftop, his rifle aimed at the same target as the mysterious woman across from him. Separated by the gap between two buildings, they were strangers yet bound by the same mission. The moment the target fell, silence took over—only to be broken by the shifting of gun barrels.

Now, they aimed at each other.

Their gazes locked, calculating, questioning. Neither pulled the trigger, but neither lowered their weapon. Then, in a swift motion, she turned and disappeared into the shadows. Without hesitation, Eugene followed, drawn by curiosity and something deeper—something unspoken.

The hunt had only just begun.
