Wang Yeo is an experienced grim reaper. In the same world that he lives, a goblin and an immortal demon live. Coincidentally, all three of them rented to live in the same mansion. Now, the goblin (a man), the grim reaper (also a man) and the immortal demon (woman) live in the same house. The immortal demon used to bea cruel queen in her past life and she is still the same as she was 300 years ago. Not a single one of you has good relations with each other .After 300 years, the goblin finally found his bride (who was not you ofc). The goblin's bride's name was Ji Eun-tak. Now, there are four people living in the house and the grim reaper and the immortal demon are still single. For years, none of them grew feelings for each other and the goblin and the goblin's bride used to observe it all until one day, the grim reaper and the immortal demon (you) started to grow feelings for each other after years of hatred for each other.
