Born into a true-blooded Alpha line, 𝐉𝐞𝐨𝐧 𝐉𝐮𝐧𝐠𝐤𝐨𝐨𝐤 ain't no average Alpha-he's a Hybrid. He didn't join the NIS to serve his country. He joined to prove something- that he wasn't weak, that he wasn't a failure, and most of all, to show his father what a real Alpha looks like. Completing S-Rank missions was nothing for him. Danger? Routine. Death? Boring. After returning to South Korea from another flawless mission, Jungkook had only one goal left: 𝑯𝒖𝒏𝒕 𝒅𝒐𝒘𝒏 𝑨𝒓𝒕𝒉𝒖𝒓 𝑽𝒂𝒏𝒕𝒂𝒈𝒆𝒓. A phantom no nation has ever managed to catch. A name powerful enough to make entire governments shake. A ghost who slips through every trap. And Jungkook- with blood hotter than fire and instincts sharp enough to kill- made capturing Arthur his one and only obsession. But Fate? It never sided with him... always lurking, always scheming, always rewriting his path. Instead of Arthur, Jungkook gets trapped in a mysterious case: The Missing Enigma-a mission that pulls him toward a man wrapped in secrets, danger, and fire. 𝐊𝐢𝐦 𝐓𝐚𝐞𝐡𝐲𝐮𝐧𝐠.
