Tracy joined the world's top task force with her unique skills in languages.
On the first day he reported for duty, he was severely intimidated by the deputy commander whose code name was Kong Sequence.
He covered his face with a mask, as cold as a cold pool,
Burning her only thought in public, forcing her to cut off the past,
The whole team laughed at her as a fledgling that had strayed into a pack of wolves.
Until a certain mission, she was shot and fell into coma.
Only then did she hear that ever-cold voice calling her nickname with a trembling voice.
Tracy was confused:
This murderous deputy commander...
He turned out to be her biological brother who had been missing for more than ten years and had protected her since childhood?
Empty sequence:
The whole world can bully you, but I can't.
But until you recognize me, I can only hurt you.
Intent: In the cold and cruel wars and missions, two scarred people, using their profession as armor and passwords as fetters, find each other and salvation through restraint and protection.
