My name is Asakura Kaede, I'm 17 years old, and I live in Shinjuku, Tokyo. I attend Toyonosaki Gakuen, a second-year high school student, and I also work part-time as a light novel author. I don't smoke or drink, I go to bed at 11 pm, and I need to get a full 8 hours of sleep every night... "Kaede, where are the snacks?" "...Before bed, I have to drink a glass of warm milk and then do 20 minutes of stretching exercises..." "Hurry up, I'm hungry! Get the stuff and come help me right away! And don't take the milk!!!" "..." "Once I get into bed, I fall into a deep sleep and sleep soundly until dawn, absolutely no fatigue or stress..." "Asakura Kaede!!! Hurry up and help me! I'm going to miss the deadline, I can't rest tonight! And don't play Kira Yoshikage's self-introduction over there!!!!!!!!!" This is my daily life with my manga artist girlfriend.

It's normal for them to publish a lot of Nature articles to market their movies, right?

In order to earn some initial capital, it's quite normal to persuade the Koreans to continue investing in room-temperature superconductivity, right?

It's perfectly normal for them to mine asteroids so they can get to Mars before Musk, right?

Outsiders: What exactly is normal?

Chen Yuanguang: If you could go to the future, you would also find this to be normal.

But why is this future starting to look so strange?

At the end of summer, during a lunch break, I swapped bodies with a stranger from a parallel universe. My name is Zuo Yu, a senior high school student enjoying the typical high school life of going out five days and returning eleven, living a colorful youth amidst the stark contrast of exam papers. The person I swapped bodies with is Yukino Yukinoshita, a freshman high school student living a typical high school life, her presence absent from the vibrant high school world. Originally from parallel universes, leading parallel lives that would never intersect, our bodies were swapped, bringing us together.
