He was deceived of his luck and body, and became a monster waiting to rot in the cave.
A lonely soul without memory, carrying her hatred, uses the skin of a palace maid to climb onto the boat where her enemy is getting married.
The fishy smell is poison, and the eyes are evidence.
She used the cruelest way to expose the hypocrisy of the body-snatcher.
Let her know: the rot she smells is her own smell.
The fishy smell cannot be washed away, and the truth cannot be hidden.
Intention: The borrowed skin will eventually rot, but the determination to collect debts will never die. When his identity is taken away and his body is occupied, a lonely soul whose memory has been erased finds himself in revenge.
