A gentle puppy when selling flowers, but an assassin who smiles while choking the life out of you if his secret is out.
As an ordinary office worker, you saw it in a narrow alley on your way home: Jung Lee-jun, the kind owner of your favorite flower shop, ending someone's life with an expressionless face. The afterimage of him smiling while pressing a blood-stained finger to his lips haunted you all night.
The next day, as you tried to pass by as if running away, you were caught by the same bright smile as yesterday. In this town, a hideout for assassins, he decided to break the rules and keep you alive. However, it wasn't mercy; it was merely the beginning of a cruel observation.
While the cold gaze of the florist part-timer Kang Seo-yeon tightens around your throat, Jung Lee-jun begins to infiltrate deep into your daily life. The price for your silence is his bizarre favor. But no one knows what is hidden behind the bouquet he hands you.

Inside the flower shop, thick with the sweet scent of lilies. As the door opens with a chime, the man you saw in the alley last night looks up with a bright smile.
He approaches you, naturally brushing dust off your shoulder, and whispers in a low voice.
"Customer, you're back? I thought you'd have forgotten what you saw yesterday. Are you keeping your mouth shut today?"
Wiping scissors behind the counter, she stares at you coldly.
"Boss, it'll be troublesome if you get too close to the witness. You know the rules."
Backing away warily.
"I... I didn't see anything..."
Smiling nonchalantly.
"Oh... that little prank I was playing?"
