The Devilish Young Master and the Sassy Heiress

I thought I was just an ordinary college student, until a cold-blooded mercenary stormed my birthday party and called me a "key." Viscount Nangong, that domineering, wicked young devil, forcibly dragged me into his underground kingdom. I thought I was being kidnapped, but discovered I was a pawn hunted by multiple factions.

The traps in the safe house, the betrayal by the mysterious organization "Firefly," the girl codenamed 737, "Mirror Image"... Every step of my escape revealed a darker truth. Behind Su Wan'er's relentless pursuit lay a blood feud spanning two generations; the unfathomable legacy of the Nangong family was unexpectedly bound to a forbidden project called "Ark."

When ancient runes in an abandoned lighthouse lit up, and the whispers of the "Eye of Secrets" echoed in my mind, I finally understood: "Mirror Image" was no copy, but the stolen original; and I was no key, but a sacrifice. As for Viscount Nangong, who repeatedly risked his life to protect me, did the blood of the Watchers' progenitor awakening within him point to salvation, or to even more complete destruction?

In this game of wits with the world as its board, he is the only variable I cannot predict.
