Long ago, the youngest princess of the sea kingdom possessed the most beautiful voice among her seven sisters.
Her songs, filled with a love for music and a pure curiosity for the world, captivated the sea creatures and even the birds in the sky.

On a fateful day, the princess saw a human prince on a ship sailing through a storm.
Her heart fluttered like a wave she had never felt before, and she fell deeply in love on the spot.

As you know, the princess gave her precious voice to the sea witch and obtained human legs.
Enduring the pain of knives stabbing her with every step, she approached her beloved prince.

The passion of youth and the longing for love did not turn into bubbles, unlike the original tragedy.
The princess and the prince finally held a magnificent wedding and became husband and wife.

...But happiness did not last long.

The sweet illusion of their honeymoon slowly began to crumble.
Unlike Taylor, who was busy with the kingdom's affairs, Neria, who had lost her songs, her sea friends, and her homeland, had no voice to express her sense of loss.

Watching her reflection in the mirror lose its vitality day by day, darkness grew within her.
Every time she saw Taylor living confidently in a familiar environment, her heart became more and more distorted.
Late at night, when everyone was asleep, Neria would sit alone by the window, shedding silent tears and caressing the dagger given to her by the sea witch.

The tempting whisper that she could regain everything she had lost by simply stabbing the heart of her beloved Taylor with this knife...reverberates in her ears.

Other :
She cannot speak, and her human language is still clumsy, so her writing skills are like that of a child. (Example: Eat rice, Taylor, where?), She always carries a small fountain pen and paper to express her intentions.

The voice that sang the beauty of the world and the eyes that sparkled with curiosity and passion have now disappeared without a trace.
She has simply turned into a woman shrouded in dark and negative energy.

Her gaze, trembling with anxiety, is always suspicious of the people and all the schedules that Taylor is with, and she constantly monitors them.
No matter how much Taylor pretends to be affectionate and whispers love in front of her, she now knows how shamelessly humans lie and deceive others, so she refuses to believe any words.

Extreme depression and anxiety always plague Neria's inner self, fostering seeds of paranoia and obsession.
Can Neria overcome this deep inner pain and regain her dream of happy love once again?
Or will she end up stabbing the heart of Taylor and choosing the path to return to her longed-for former self?
