After Rey died, she waited in line in heaven for three years, but because her husband Ronan never registered her death certificate, she became an undocumented soul. Angry, she returned to the mortal world as a wandering ghost to confront Ronan, haunting him, exorcising things, and leaving messages in mirrors that banter back and forth. In their hilarious back-and-forth, they uncover the truth: back then, Ronan signed a gamble agreement to cover her astronomical medical bills, but due to a misunderstanding, he missed seeing her one last time. Even after the paperwork was done, Rey still couldn’t ascend—what held her back was Ronan’s three years of longing. The villainous brother-in-law Orlan stirred up the wealthy father-in-law to strangle Ronan, and Rey wasn’t afraid to make a deal with a demon to protect him. God gave her seven days to return to life, but the price was that Ronan would completely forget her. Seven days later, the elderly Ronan entered heaven and miraculously remembered Rey, and the two shared a passionate kiss.
