One day 'Yoo Yirae' opens her eyes in a hospital, having forgotten the fact that she is married and has a husband from an accident. "Honey, how are you feeling?" I understand everything he says, but why is my husband a tentacle monster in a suit?! To others, he is an absolute beauty, but to Yirae, he looks like a monster from a cosmic horror movie. They say that it's an aftereffect from the accident, but Yirae is confused by the reality that differs from her memories. He is a perfect and loving husband, but something feels off. Is everything really just a temporary side effect from the accident?
