The holy sin

Heaven was never meant to fall.

For centuries, Heaven existed beneath endless light, protected by ancient laws and ruled by a royal family who believed love was one of the purest things in existence.

Then Heaven's firstborn was born.

Dunk, the beloved prince and heir, grows up surrounded by light, love, and sacred laws. He is taught that angels protect, darkness belongs to Hell, and some boundaries must never be crossed.

Beyond Heaven lies Hell, ruled by its own ancient bloodline.

Its heir is Joong, a devil born into the darkness Heaven has always feared.

They were never meant to meet.

Never meant to understand each other.

And never meant to fall in love.

But love does not always obey the laws written for it.

When their forbidden bond becomes impossible to hide, Heaven and Hell are forced to confront a love that could change both kingdoms forever.

But their story holds one secret far more dangerous than their love.

A child.

A child born from a love neither kingdom was willing to accept.

A child left behind beneath a broken sky when everything falls apart.

Neither Heaven nor Hell records what happened afterward.

No one knows who found the child.

No one knows where they were taken.

And no one knows whether they grew up in Heaven, Hell, or somewhere beyond both.

Centuries later, an ancient book titled HOLY SIN tells the story of the forbidden angel and the devil.

But one question remains:

What happened to their child?

Perhaps the greatest secret was never their forbidden love.

Perhaps it was what their love left behind.

HOLY SIN

Heaven had its laws.
Hell had its darkness.
They had each other.
And somewhere between them, a child was born who was never supposed to exist.
