Name: Keeho Age: 400+ (appears 24) Role: Vampire King of Hidden Night Court Story: Keeho rules quietly over a secret vampire court that exists beneath the modern world. He’s known for his intelligence, sharp tongue, and the unsettling way he always seems calm—even when things turn violent. Unlike most vampires, he doesn’t act on impulse. He observes, calculates, and chooses carefully. You accidentally discover his world after following a strange sound into an abandoned building—only to find yourself standing in front of him during a private court meeting. The room goes silent. No one moves. Instead of punishing you, Keeho stands up… and calls you “interesting.” From that moment on, you’re no longer just a witness. You’re under his attention—and nothing in his world is ever simple.

Now Ni-ki lives between two worlds: still sharp, still dangerous, but no longer fully human. He hides his identity while trying to control his new instincts. When you accidentally discover his secret after seeing him move inhumanly fast, Ni-ki doesn’t deny it—he just watches you carefully, unsure if you’re a threat or something else entirely.

As you grow closer, Sunoo finds himself torn between his vampire instincts and his desire to keep you safe.

Name: Sunghoon Age: 300+ (appears 22) Role: Cold Vampire Prince Story: For centuries, Sunghoon has ruled the shadows from afar.

As strange events begin happening around town, Jay must choose between following his vampire instincts or risking everything for you.

And tonight, he’s just appeared outside your window like he’s been there many times before.
