Goblin: the lonely and great god

When a powerful desire in dwells in things touched by mortal souls, they become goblins
A blade smeared with blood from countless battles...
was enchanted with a powerful desire be dwell with its master's blood.
Only the bride of the goblin will be able to draw the blade.
Once drawn, everything will turn to ashes, and peace will be granted.
"Physics of Love" a poem by Kim In-Yook
“Mass is not proportional to volume. A girl as small as a violet. A girl who moves like a flower petal is pulling me toward her with more force than her mass. Just then, like Newton’s apple, I rolled toward her without stopping until I fell on her, with a thump. With a thump. My heart keeps bouncing between the sky and the ground. It was my first love.”

The Plot (soruce: http://asianwiki.com/Goblin_(Korean_Drama))
In ancient times, Kim Shin (Gong Yoo) is an unbeatable general in wars, who was appointed to protect the young King (Kim Min-Jae). Unfortunately, the young king is jealous of Kim Shin and kills him. Kim Shin becomes Dokkaebi (Goblin), possessing an immortal life. At first he thinks that he is blessed, but he realizes that he is cursed.
Closer to the present day, Kim Shin has waited 900 years for a human bride to end his immortal life. One night, he saves a dying pregnant woman (Park Hee-Von) who is destined to die. Meanwhile, the Grim Reaper (Lee Dong-Wook) is unable to find the dead pregnant woman. The woman gives birth to a baby girl named Ji Eun-Tak (later played by Kim Go-Eun). 9 years later, Ji Eun-Tak lives with her mother and is able to see ghosts. One night, her mother suddenly dies. On that night, she meets the Grim Reaper.
In the present day, Ji Eun-Tak is a high school student. She still sees ghosts and hears their whisper of “Dokkaebi’s bride.” She now lives with her aunt’s family, but she is mistreated by them. On her birthday, Ji Eun-Tak sits by the sea with a lighted birthday cake. At that time, Kim Shin suddenly appears in front of her. Kim Shin does not know why, but he can hear her voice and appears in front of her against his will. Coincidentally, Kim Shin lives with the Grim Reaper at the same house.
Now, Kim Shin appears in front of her against his will, whenever she turns off the lights. One day, Ji Eun-Tak tells him that he is Dokkaebi and she is his bride.
