During class, a mysterious young woman walked in, and during the short pause called by Sato Sensei, this sudden appearance set the online discussion board of Naniwa University's Literature Department on fire. As the students were buzzing with excitement, an alumnus who had finished school years before uncovered the identity of the young woman.
"— That's Mr. Sato's wife, Mrs. Sato, the woman he has been married to for over forty years."
The students were shocked by this news. 'Wait, Mrs. Sato is actually in her sixties? But she looks so much younger!'
Before they could whip themselves into a frenzy again, another alumnus posted a newspaper headline that had once grabbed everyone's attention: "The Fifth Time Traveler—A 28-Year-Old Woman Jumps Forty Years into the Future." She didn't say anything more.
Creation is hard, cheer me up!
