My name is Ling Xi, a time traveler. After arriving in a world of pre-collapse civilization, I originally just wanted to cling to someone powerful enough to survive, so I could get a spot in a hibernation chamber during the final cleanup.

Later, Miss Mobius, a scientist from the Fire Moth, seemed interested in me, so I inexplicably married her. My married life was pretty simple. Besides the routine tasks, I just ate noodles with Kevin, played with Alicia, and at most, cooperated with my wife on some experiments. Until one day...

a girl who looked very much like my wife returned home and smiled at me, saying, "Honey, don't you recognize me? I'm Mobius, the real Mobius, and... the only Mobius!"
