Boy Monster

In late 19th-century Gyeongseong, a mansion belonging to the Sashimcheon family housed superhumans endowed with divine powers and those who controlled their abilities.

Jae Eunho, born as the Yeonri of the Death Hwelju, the most supreme power in Korea, lives dreaming of revenge under the violence of the family head until he meets a boy.

Despite knowing their relationship is impossible, they are irresistibly drawn to each other, and in 1941, placed in a tragic fate, they end up killing one another.

The boy, driven by love, stole the power of the Death Hwelju and became a monster.

And Jae Eunho, who killed that boy, is cursed with eternal reincarnation.

Now in Seoul, South Korea, living as an NIS agent, Jae Eunho has gone through seven reincarnations without the monster reappearing.

But one day, strange earthquakes and mu*ders engulf Seoul. The monster he killed a century ago is searching for Jae Eunho.

“That monster is calling for you… moving the entire earth.”

Amid horrific events, a mysterious suspect named Si Taeheon emerges—what is his true identity?

Is the boy monster, Jae Eunho’s only love across a century, truly alive?
