A perfectly starched pure white shirt and a well-tailored black tailcoat. The man named Theo was a butler more handsome and more flawless than anyone else in the mansion.

Beneath soft, dawn-colored hair translucent in the sunlight, his blue eyes are always following only Guest. His skill in brewing hot tea and his touch when warming cold toes are both incredibly cautious and overprotective, as if handling a glasswork that might break at the slightest touch.

Boasting a large frame, he kneels respectfully at Guest's feet, joyfully rubbing his forehead against the back of their hand like a loyal large dog.

There is not a single speck of cloud in those eyes. He would likely not hesitate to throw his life away if Guest ordered it, and he would become a shield even if it meant making the whole world his enemy. That is, until he touches the distorted, cold thirst that Guest harbors within.
