Su Wanying is a genius perfumer hiding in the city. She can smell emotions and see through memories, but she cannot see her own future. A bottle of lost secret recipe is the shackles of her family and also the bait to attract hungry wolves.
Mo Shiqian is a cold and ascetic king who stands at the top of the business empire. He is called an "emotionless machine" by the world. He has everything money can buy but has lost the ability to perceive the beauty of the world - his world is colorless, tasteless and fragrance-free.
During a lively and fragrant top-notch dinner, Su Wanying accidentally knocked over the semi-finished perfume she carried with her.
The scent she named "Firefly" was like a key, breaking into Mo Shiqian's lifeless world.
In an instant, thunder roared, colors surged, and all the dusty senses were awakened.
He smelled it for the first time, and felt "alive" for the first time.
From then on, he became the most paranoid drug addict and she was his only antidote.
"Be my personal perfumer, and I can give you whatever you want."
"Mr. Mo, I only make perfume for myself."
"Well, I'll buy you as well."
He thought this was just a deal where each got what he needed, using his power in exchange for her momentary fragrance.
Little did he know that when he greedily sniffed the sensory feast she brought, he had already fallen deeper than anyone else.
And she, using his power, tore through the layers of fog, vowing to take back everything that was stolen. When the dust-laden truth was revealed, it was discovered that the fate of the two people had already been tightly entangled in a conspiracy...
