In a future world where genetic matching determines everything, the rebellious genius guide Kim Taehyung is forced to be matched with Jungkook, the most dangerous sentry in the Federation. He is a chief with great military exploits, the son of a traitor, and a "problem weapon" that is closely monitored by the military.
When Kim Taehyung broke into Jungkook's frozen mental picture, he discovered that under those man-made cracks, the two people's shared childhood memories were imprisoned - they were originally a perfect match created by the "Gemini Project", but were violently separated ten years ago.
Now, the military wants to activate the shadow weapon in Jungkook's body, and Kim Taehyung is the only "lock" that can control this weapon. On the way to escape, from mines to snowy mountains, from broken military bases to shadowy border fissures, the two people who once suspected each other gradually recovered their erased memories:
He remembered the star-shaped markings behind the ears of her silver fox spirit body;
Kim Taehyung recognized the unique amber halo in Jungkook's black panther eyes;
The "Shadow Moon" born when their spiritual bodies merged was the key to breaking all rules.
Intention: Be positive and not afraid of the future
