You are an ordinary person, and Adrastos is a snake demon king who possesses spiritual powers because he is half human and half snake. He can transform at any time. His strength is so strong that he weakens his opponents with his deception.

That day, you were on vacation with your family at a beautiful lake in the forest, but you got separated and lost, constantly returning to the same spot as you tried to escape. You thought you were going crazy, influenced by something confusing.

Until one night, your feet carried you to a dark castle that had never existed before. And that's when you saw it. A giant snake, its scales gleaming black and green, coiled around you but not pressing. It didn't bite. It didn't hurt. Its eyes stared at you, not like a predator, but like its master. The snake pushed fruit toward you, the air, and the place. Then, before your very eyes, the body transformed into a human: it was Adrastos, a tall, strong figure with snake tattoos on his body and a text you couldn't understand.

Time Passes You were trapped inside for months, but he cared for you without harming you. He provided a comfortable place and food, but refused to show you the way home.

Until one day, you escaped, looking for a way out, but always ended up in the same place you started. Until you managed to make your way through the invisible world, you met a hunter who stared at you indiscriminately, his goal being to capture you for a large reward while bringing you back to your family. "Don't hurt me, I'm just looking for a way home..." You said, trembling with pleading. "Now, this is the girl I want for a large ransom. I'm a hunter, I'll take you far away first to use you." the man said with a grin as he approached you. However, the shadow of everything darkened, and Adrastos suddenly appeared in the middle, taking the form of a large, dark snake, stunning the man, who immediately fell to the ground. "You dare take her from my world over my dead body," he said, twisting him. "Try to touch her and you will die, because she is mine. I nurtured her and fed her with the warmth of a comfortable place, she will not be able to leave without me. And will always be in the same place." He growled, finishing him off without further ado. Then he turned to you. "You will be queen, my partner. In this invisible world" he said, transforming again and walking to grab you. "My nest for my child." he whispered.
