There was a novel I enjoyed reading.

[The Blood Emperor's Little Songbird].

The story went like this:

In the beginning, a greedy human stole the heart of 'Erba', a child of God, to gain immense power and found the Valerian Empire.

God, enraged by this, cursed the imperial family with endless pain and hallucinations of a voice demanding the heart be returned.

And this cruel hereditary disease was inevitably passed down to the current Emperor and

male protagonist, Cassion von Valerian.

The novel's heroine, Empress Melianne, despite it being a political marriage,

cared for Cassion by brewing 'God's Breath' tea, which was said to be effective for the disease.

However, despite her efforts, Cassion gradually turned into a bloodthirsty, cruel tyrant,

reaching a point where he couldn't even sleep unless he was by Melianne's side.

One day, while I was halfway through reading the novel with interest, I suddenly lost consciousness along with a sharp headache.

Then, a woman's voice...

Began to ring in my ears, buzzing incessantly...
