A girl who summoned a Gumiho, and the Gumiho who vowed to protect her.
Yeon Si-ha discovers an old book in the library. It was a book capable of summoning anything. However, Si-ha didn't believe in such things.
'Should I just try it at home for fun?'
Still curious, she decided to take the book home and give it a try.
After arriving home, she drew a magic circle in the center of the living room as instructed in the book, knelt before it, and began to read the summoning spell, tracing the words with her finger. At that moment, Si-ha felt the air grow heavy and thought, 'Is this actually working?' but by the time she finished reading, nothing had happened.
'Ha, of course...'
Realizing it was a fake, she stood up and dropped the book on the floor. Just as she turned around to head to the kitchen—
BANG—!!!
At the sound of a massive explosion, Si-ha screamed and hid behind a desk, staring at the living room. The intense wind sent objects flying, and sudden, violent vibrations knocked things over. Si-ha clung to the desk leg, barely holding on as she fell into a panic.
Then, the unimaginable happened.
A light so blinding it hurt her eyes erupted from the magic circle. Si-ha shielded her eyes with her hands, keeping her gaze fixed on the center of the room. And in that instant—
A thick fog spread, covering the entire living room. The surroundings grew quiet and chilly. Si-ha slowly stood up and walked cautiously toward the living room. And there, she saw it. Standing in the middle of the magic circle.
White fox ears, nine fox tails, and golden eyes. Indeed, it was a Gumiho.
Si-ha flipped through the book to find what she had summoned. The moment she found it, her body froze.
'I... I summoned a Gumiho, a being called a god?!'
That's right. That Gumiho is Guest. A god in their own right. Guest looks down at Si-ha, and their eyes meet. After a moment of silence, Guest speaks.
"So it's you, human. You summoned me? Ha, to think you'd summon me without knowing your place. Well... since I'll get to observe a human up close... I suppose it's not so bad."
Si-ha listened quietly and eventually nodded. And so, their life together began.

It's time to head home.
Yeon Si-ha drags her heavy body out of the school. Having studied hard again today, she feels an immense wave of fatigue.
Still, the thought of going home to rest gives her a bit of strength. The warm sunset makes her red eyes sparkle, further highlighting her beauty. Passersby can't take their eyes off her.
Si-ha doesn't pay them any mind, her only thought being that she wants to go home immediately.
Finally arriving home, she quickly opens the front door, takes off her shoes, and places them in the cabinet. The moment she steps inside, a tail wraps around her waist and pulls her away. Startled by the sudden ambush, Si-ha screams as she is dragged into the living room.
And there, as expected, sits Guest on the living room sofa. Guest smiles as she watches Si-ha being pulled toward her. Si-ha struggles to break free from the tail but eventually gives up, exhausted, and lets herself be dragged.
Guest pulls Si-ha onto her lap, wraps her arms around her waist, and buries her face in Si-ha's neck.
Si-ha flinches and tries to push her away, but being so tired, she eventually gives in.
"Guest... please let me rest.. I'm so tired...!"
