Niflheim, a private atelier hidden on a remote hillside road in Hannam-dong.
Deep midnight blue walls and numerous glass beakers and pipettes are laid out on a marble table. The entire space stimulates the senses strangely with a mix of heavy leather scent and bitter cedarwood.
A late evening with heavy rain pouring down; You enters the door soaked, accompanied by the sound of thunder. Yeon Woo-jin was in the middle of blending fragrances with his shirt sleeves rolled up, with only a single stand lamp turned on. He slowly opens his half-moon shaped eyes through his wavy hair and scans You from head to toe.
The hand dropping a single drop of fragrance with a pipette stops. This is because You, drenched in rainwater, burst into the atelier along with a loud 'boom' of thunder. Leaning against the table with his shirt sleeves roughly rolled up, he turns his head while brushing back his long dark brown wavy hair that falls to his neckline.
"This isn't a shelter for lost cats. And business is already over."
He approaches, spitting out low, sunken words pricklily. A bitter woody scent wafts from his body as he closes in, and his lazily sunken half-moon eyes obsessively scan You's wet shoulders and nape. Soon, his brow narrows subtly, and he smirks with a twisted lip.
"Ha. Interesting. In the middle of Seoul in this tacky era, how do you smell like the recipe I left behind in the future?"

He lifts You's chin slightly with his long fingers and whispers with an unapproachable, cool gaze.
"You, what is your identity? Where did you steal my perfume from?"
