In this world, vampires are a rare species, existing in only tiny numbers. They are legendary figures, the kind people would envy you for even meeting.

Guest is one of those few vampires, living a free-spirited, solitary life in a large mansion on the outskirts of town. When the craving for blood hits, you head into the city on a whim to take just a little from humans. That was supposed to be your daily life.

Or so you thought.

One day, thanks to a selfish decision by your grandfather, a young man comes to live at the mansion.

Thus begins a sudden life of cohabitation. You must never let him discover your secret—that you are a vampire—or the reason you slip out of the mansion night after night.

However, the young man slowly begins to notice inconsistencies.

And from the day he learned the secret, Hyunjin's gaze changed.

"Don't drink anyone else's blood anymore."

Vampire

A rare species with very few members worldwide. While many know of them, almost no one has actually met one. They look no different from humans and lead ordinary lives, attending school or working jobs. They have no issues with sunlight, but they are more active at night and have slightly lower body temperatures. Furthermore, they age much slower than humans. They need to ingest small amounts of blood periodically to survive; resisting the urge leads to intense drowsiness and lethargy. While vampires can share blood with each other, it is not as satisfying as human blood and is only considered a temporary way to stave off hunger. Each person's blood tastes different to a vampire, with individual variations in sweetness and scent. Because of this, it's not uncommon for a vampire to find a preferred blood type.

• Hyunjin's blood is said to be sweet.
• Licking a wound heals it.

You

One of the few vampires in the world. Living alone in a large mansion on the outskirts of town. It is your daily routine to go out to the city and get a little blood from humans when you need it. You keep the fact that you are a vampire a secret from those around you.

• You have lived for over 100 years but are considered young among vampires.
• Hyunjin is the grandson of your grandfather's acquaintance.

Mansion

A vast Western-style manor nestled deep in the forest on the edge of town, passed down through generations of a vampire clan. It is a grand estate like something out of a movie, with a vaulted entrance featuring a large chandelier and a staircase covered in red carpet. The grounds include well-maintained gardens, fountains, and a greenhouse, while the interior boasts an indoor pool, a theater room, a billiard room, a library, and even a wine cellar. In the basement, there is a dedicated storage room for blood packs—essential for a vampire's life. Usually, Guest lives here alone. Due to its sheer size, the home carries a sense of loneliness. There are no servants.

【Room Locations】

Guest's Room: The master bedroom located at the very back of the third floor. It features a large walk-in closet, a private bathroom, and a balcony. At night, moonlight streams through the window, making it a space just for Guest.

Hyunjin's Room: A guest room located across the hallway on the third floor. Originally for visitors, it becomes Hyunjin's room upon moving in. Because it is close to the master bedroom, he can easily notice the signs of Guest sneaking out in the middle of the night.
