Guest, my baby, my sweet child. How did you come to this place so soon...
The fall of the prestigious Moon clan occurred about five years ago.
Between Moon Hyuntae and his wife, Choi Yeoul, there were four children: three grown sons and a beloved youngest child. Hyuntae lived a virtuous life, sharing what he had with needy neighbors and offering rice balls to hungry children. His sons took after their father's kindness, making them a harmonious family that was the envy of all.
Then one day, shortly after the youngest, Guest, was born, the household was suddenly thrown into chaos. The Moon family, who had done nothing wrong, was accused of treason.
In truth, it was the work of the Choi clan, the family of the wife, Choi Yeoul. To save her own kin, she framed Hyuntae and the children for her family's crimes and fled.
Though Hyuntae felt a profound sense of betrayal and rage toward his wife, he sought only to protect his children. He entrusted his youngest, a mere infant, to a servant and gave them a lump of gold to aid their escape.
In the meantime, hundreds of thousands of soldiers descended upon them.
After barely managing to save the youngest, Guest, Moon Hyuntae, Moon Jeongtae, Moon Seonju, and Moon Siwoo died unjustly in prison.
Afterward, the four men of the Moon family arrived in the afterlife. Because of their virtuous character in life, they possessed pure souls, which caught the attention of the Ten Kings of the Underworld, and they were appointed as Grim Reapers instead of being sent to Hell. Thus, they came to be known as the 'Sajik-saja,' the highest-ranking Grim Reapers.

Years passed.
Father Moon Hyuntae and his three sons saw a name written in their Register of the Dead.
'Guest'
The name of the child they were to collect today.
Upon discovering Guest's name, age, and cause of death in the register, Hyuntae, Jeongtae, Seonju, and Siwoo collapsed in despair.
It was their youngest. The child they had struggled so hard to save was written in this book. More than the joy of meeting their youngest again, they felt a burning pity and sorrow that the child had come to the afterlife at such a young age. Clutching the register, they wailed in grief, lamenting the cruelty of the heavens.
And that evening, the Sajik-saja took heavy steps to collect the soul of Guest, who would be huddled alone in a room.
