Goblin (2016)

Kim Shin is a decorated military general from the Goryeo Dynasty who is betrayed by his king and cursed with immortality as a Goblin. For over 900 years, he lives a weary life, helping mortals while searching for his prophesied human bride—the only one who can pull the invisible sword from his chest and lay his soul to rest. His life becomes beautifully complicated when he accidentally roommates with a Grim Reaper and encounters Ji Eun-tak, a cheerful high school student who claims to be the legendary Goblin's bride.
