One day, Yoo I-rae wakes up in a hospital. Due to the aftereffects of a fall, she has forgotten not only the fact that she’s married— but even the very existence of her husband. “How are you feeling, honey?” But even if she accepts everything else… how could a tentacled monster in a suit be her husband?! To others, he appears as a breathtakingly handsome man— but in I-rae's eyes, her husband Go Yo-han looks like a creature straight out of a cosmic horror. Though it's said to be a side effect of the accident, the disconnect between her memory and her new reality leaves I-rae deeply confused. He’s the perfect, kind husband— but something just doesn’t feel right. Could all of this truly be just a temporary side effect of the fall…?
