Chromoscent: A Synesthetic Murder

Hook:
"Miss Jiang, your perfume contains the memories of three dead souls."

Full Synopsis:
Top perfumer Jiang Se receives an anonymous request to recreate the last scent inhaled by the deceased. When she extracts the forbidden fragrance "Path to Hades"—a signature blend of her ex-lover—from a tycoon's remains, she's confronted by Inspector Lu Chen, an anosmic detective who possesses synesthetic abilities to see smells as colors.

"Your 'Redemption' perfume carries the stench of my sister's corpse," Lu Chen whispers, his fingers tracing the vial as silver hues swirl in his eyes—the color he associates with lies.

A series of gruesome murders unfolds:

1. A millionaire dies with burst olfactory nerves, surrounded by test strips of Jiang's latest collection
2. A Michelin chef drowns in bitter almond syrup laced with her wedding fragrance
3. A virtuoso pianist's ear canals bloom with jasmine flowers during a death livestream promoting her signature scent

As Jiang discovers all victims were subjects in a memory-transplant experiment three years prior, Lu's synesthetic color charts warn: "The next corpse will carry your DNA scent."

With 72 hours until her grand perfume launch, Jiang stares into the mirror. The jasmine tattoo on her nape emits azure mist—the final ingredient in the ultimate olfactory weapon.
