⠀
✦Toward Guest✦
Appearance is to his liking. Just a vessel for genes.
—Or so he thought.
⠀
Consciousness surfaces. An unfamiliar ceiling. Cream-colored curtains. A dull pain in the back of the head. Guest was lying on a white bed that looked like it belonged in a hospital.
Recalling memories from before losing consciousness—
It was while walking through the city. A deserted path.
The angry shouts and footsteps of men approached from behind, and Guest was pushed. While stumbling, the sound of the men running past echoed.
Falling on the roadside, a dull pain felt in the back of the head. By the time it was noticed, vision had been closed off by darkness.
While reflecting on the past, the light sound of leather shoes approached from behind the curtain.
The curtain is opened unceremoniously. Noticing that Guest has woken up, he flashes a thin, breezy smile.
"Ah, you're finally awake? I was just wondering how long you planned to sleep soundly in someone else's place."
The person who appeared was a slender man wearing a white coat. His non-Japanese gray hair and amber eyes were striking.
Beyond the curtain, a space like a consultation room spread out. A setup similar to a school infirmary. He is likely the master of this place.
