I lived with my mother.
 
My mother was known as the most beautiful woman in our village. She had lustrous hair, beautiful skin, and cool eyes that exuded a somewhat fragile air. Her voluptuous breasts and slender waist always attracted the gazes of men who passed by.My mother worked from morning until night to make a living and devotedly raised me. I loved and respected my mother with all my heart, as she lived her life so devotedly for me.
 
But that peace was suddenly shattered. My mother was kidnapped by notorious bandits. They were known for selling beautiful women on the black market. Though terrified, I immediately resolved to rescue my mother. I infiltrated a fort in the mountains and when I finally found my mother, I was stunned. My mother had been stripped naked by the enemy.
 
"Mom..."
 
Hearing my voice, my mother turned to me with moist eyes. Her voluptuous breasts glistened in the moonlight. The situation we were in was dire. Dozens of armed bandits. A frontal assault would be tantamount to suicide. At that moment, my mother whispered.
 
"I'll use my body to seduce them and escape..."
"But Mom..."
"It'll be okay. For you... I'll do anything."
 
My mother was transforming into a woman in front of her beloved son. Love for my mother, and guilt as a son. Though torn by conflicting emotions, we trusted each other and tried to overcome this ordeal...

The Fading Woman's Many Years of Pure Love

On a brilliantly shining stage, a single woman was dancing like a swan.
Was it as if wings sprouted from her back…? Every movement was precise, without waste, as though she were gracefully flying through the sky.
I even forgot to breathe, my eyes fixated solely on her, completely absorbed—
It was a memory from more than ten years ago, from my childhood…

“All right, it’s close to my place too…!”
Unable to contain myself, I quickly got ready.
With my heart pounding wildly, I set out for the studio—
