Kim Shin is an immortal “goblin,” and has the rather honorable title of being the Protector of Souls. His roommate Wang Yeo also happens to have the equally lofty, if thoroughly opposing, title of Angel of Death, and he acts as the storied grim reaper that claims souls. However, both these devilishly handsome angels have a problem: Wang Yeo has amnesia and Kim Shin wants to end his own (immortal) life. Unfortunately for goblins, the only way to defeat immortality is to marry a human bride. For that purpose, Kim Shin decides to win over Ji Eun Tak an optimistic high school girl who he thinks will be the priestess that ends his cursed existence. Now, once responsible for protecting souls and watching them pass, Kim Shin now tries to send his own to the afterlife. But when a slightly complicated method of suicide starts turning into true love, will our immortal goblin begin to regret his decision--where acting on that very love ultimately means the end of his life?
One of the main characters come from a "Cinderella" style background; kind-hearted character growing up in an incredibly (often exaggeratedly) abusive and greedy step-family.
When two of the characters are feeling sad and confused due to their romantic lives, they both take multiple psychiatric drugs at the same time that are for disorders that they do not have.
A pregnant person and her baby die in the first episode but are brought back to life by a goblin. The grim reaper turns up to collect their souls but finds they’re gone since they’re still alive.
The main male character is like 900 years old and the female lead is still in high school when they meet. They really play up her youthful energy and she is seen in a school uniform in some scenes.
