Erica's sister is a blooming flower in the spring. When she smiles, half of the garden loses its color.
She stands beside her sister Siren as a protector. Everyone says that she is the most caring and trustworthy guard of the Pearl of the Sea. Even if her sister doesn't need her, she stays by her sister's side in the most humble manner. For countless nights, Erica closed her eyes and pressed her cheek against her sister's knees, listening to the songs of the sirens. She hugged her sister's waist, and her arms wrapped around her like a boneless snake. The silver scales on her forearms reflected the phosphorescence that seemed to be flowing in the water, like a flower attached to the bones to absorb nutrients from the host.
She is willing to share everything with her sister, except for one thing. That was the deepest and most obscure darkness hidden in Erica's heart.
Only Erica herself knew that she had cursed her sister to die in the most painful manner on countless moonless midnights.
