Age of Texture The Butterfly Mark

A broken office worker learns to read the scars of the world — and grows strong enough to face the ancient power feeding on them.

The premise

The world remembers pressure, grief, and wounds.

Siwoo Han was an office ghost: ignored at work, overworked by everyone, and slowly disappearing from his own life. Then a dying saint's butterfly marked his palm.

Now the world has texture.

A cracked mug remembers fear. A forgotten building hums with grief. Crowded subway cars carry more than exhaustion.

Guided by a sharp-tongued cat named Cello and a hidden tea house called Abraxas, Siwoo must learn to read the scars of the world before the power that broke them finishes the job.

Not LitRPGNo system windows. No stat screens. The progression is slow, tactile, and character-driven.
Found familyA tired office worker, an ancient cat, a guilty tea master, and companions who keep choosing each other.
Relic mysteryPlaces are not dungeons. They are wounds — each with its own pressure, memory, and scar.

Core cast

People who begin as survivors, not heroes.

Rain, paper grain, wet concrete, small supernatural light, and faces carrying more pressure than spectacle: the cast is built to feel intimate before it becomes mythic.

Beatrice

The lost princess

A second face of the same wound: luminous, ceremonial, impossible.

Sacred sabers

Light, memory, and inheritance.

The relics appear as sacred light-blades rather than ordinary steel: Siwoo's silver-white column of light and Dean's jade-green resonance.

The butterfly mark becomes a quiet column of light rather than a heroic sword pose.

Dean · Jade-green

A controlled, guilty resonance in a sealed underground passage.

The world scars

Every place is a wound with its own texture.

The journey grows beyond Seoul, but each destination stays intimate: a place marked by pressure, memory, and the question of what survived there.
