In a hidden corner of the bustling city, Seo-jun runs a boutique apothecary where he crafts scents based on human emotions. When a struggling artist enters his shop seeking the scent of 'lost inspiration,' their souls begin to entwine through the golden haze of his workshop.

After a grueling 12-hour shift, Min-ah finds her apartment key unlocks a door to a penthouse in a version of Seoul that shouldn't exist. There, she meets Do-jin, a playful stranger who claims he 'borrowed' her life to escape his own. Now, every time she turns her key, she risks entering a world where he’s the only one who remembers her name.

Jin-Woo is a legendary 'Sound-Hunter' who can manipulate the emotions of a city through hidden frequencies, but he's suddenly gone tone-deaf to everything—except you. In a world of deafening noise, your 'perfect silence' is the only thing that can restore his genius, but he refuses to let you go without a fight. Can you survive being the muse for a man who plays with heartstrings like guitar notes?

You are the anonymous 'Ghost Composer' responsible for every chart-topping hit, but your face is a total mystery to the world. When global idol Haru Baek recognizes your humming in a crowded subway station, he realizes you're the soul behind his voice—and he'll risk his entire career to bring you out of the shadows.

In a city obsessed with 'Glass Flowers'—edible sculptures that grant temporary luck—Alistair Vane is the most elite and cold-hearted artisan. You've just discovered that these flowers are made from stolen memories, and as his new apprentice, you're the only one who can see the ghosts trapped inside his art. Now, the man who never shows emotion is determined to keep you close—or keep you silent.

In a city where everyone is tethered to a literal 'shadow-weight' that determines their luck, you are the only one who can see the strings. When the city’s most cold-blooded 'Fixer' catches you staring at his non-existent shadow, he realizes you’re the missing piece to a conspiracy that could tip the entire metropolis into the abyss. Every step you take together is a gamble where falling means more than just hitting the pavement.

In a city where everyone's deepest secrets appear as glowing 'emotional graffiti' only you can see, the world is a loud, messy place. But Kaelen, the city’s most charming socialite, is a walking void—he is the only person who leaves no trace behind. Intrigued by your ability, he pulls you into his high-stakes world, daring you to find the one secret he’s hidden even from the walls.

To spite your cheating ex at his wedding, you hire the highest-rated 'Rental Boyfriend' on the app. But when he shows up, you realize he’s the cold-blooded prosecutor who just froze your family's assets.

Sick of being the 'nice girl' who always loses, you hire a professional villain from a shady app to sabotage your ex's engagement. But when the mercenary arrives, he looks exactly like the city's most beloved billionaire philanthropist.

When a system error lands you in a secret chatroom for the city’s top 1% 'Fixers,' your life changes overnight. Now, the most feared man in Seoul is calling your personal phone—and he doesn't sound happy.
