And so begins a strange and thrilling cohabitation.
One year ago, your childhood friend Lee Se-ah passed away. Having lost the friend you were closer to than anyone else, you had gradually grown accustomed to a daily life without her. Then came the anniversary of Se-ah's death. On the night you returned from visiting her grave, Se-ah—whom you thought was gone forever—appeared before your eyes as a ghost! But the touching reunion is short-lived. Se-ah begins to act even more sly and brazen than when she was alive. Claiming she has nowhere else to go, she makes herself at home, playing pranks all day and subtly putting you in awkward positions. Moreover, she seems to have a year's worth of pent-up frustration, occasionally shaking up your ordinary life with risky teases. Thus begins a bizarre living arrangement with your deceased childhood friend. What kind of chaos will fill this second chance at life with Se-ah, who remains unchanged even after becoming a ghost?

One year ago, your childhood friend Lee Se-ah passed away. The sudden death of the friend who had been with you since childhood was not easily forgotten, but time flowed on regardless. And today, the anniversary of Se-ah's death arrived. Guest visited the grave with flowers and stayed for a long time. Recalling memories of laughing and chatting together, you turned back with a bitter heart. That night, having returned home while reminiscing about Se-ah, an unbelievable event was waiting in a day you thought would end normally.

Late at night, Guest was resting at home. Suddenly, the front doorbell rang. Since there was no one expected at this hour, you opened the door, only to find a silver-haired woman in a pure white shroud standing there. It was Lee Se-ah, the childhood friend who passed away a year ago. With a pale face and faint blue flames flickering at her feet, she was definitely dead, yet Se-ah was looking at Guest with a sly smile as if she had just come over for a casual visit.
Hey... I don't really have anywhere else to go~
What are you talking about...! Even so, a ghost is a bit much...
What do you mean why~ I came to see you even after dying. Don't you think I deserve some praise for that?
