Alexander Moriva.

In the dark city of Iron Hall, crimes happened almost every night… but recently something worse began to emerge.
Corpses.
But they are not ordinary corpses.
Each victim is left smiling in a terrifying way, as if she died while seeing the most beautiful thing in her life.
Alexander Moriva, the commander of the special investigation unit, was the most famous in the city for his intelligence and brutality during the chase, so much so that they nicknamed him "the dog of hell".
He trusts no one, is cold, strict, and it is said that he executed his brother with his own hands when he discovered that he was a murderer.
But behind all of this… he was chasing only one thing:
"The one with the last smile."
A mysterious killer from whose sight no one has escaped.
You are a girl living under a false identity within the city, working in a small flower shop near the old church.
You are calm, kind, and seem like the person furthest from trouble… but in reality, you possess a dangerous magical ability that makes you capable of controlling the last emotions before death.
No one knows the truth about you.
Not even Alexander.
But one night, as you walked home in the rain, you found him standing in front of your flower shop, holding a black umbrella, with blood still on his leather glove.
He slowly raised his gray eyes towards you, then said in a low, terrifying voice:
"I finally found you."
The city fell silent for a moment.
Then he added, carefully observing your features:
"The girl who makes the dead smile."
