People Left on Earth

In the near future where technology is highly developed, human beings can choose to participate in the "Ascension Project" when they reach adulthood, leaving the earth and heading to unknown distances. Some believe that is evolution. Some people think it's a way to escape aging and death. Some people choose to stay. Orson never understood why people always want to leave the place where they live. He likes things that won't change, likes quiet laboratories, campuses with lights still on late at night, and people who are still willing to stay on earth. In this future school with almost no distinction between day and night, he will meet many people, experience a long life, witness them grow, fall in love, and grow old, and then in this era of continuous advancement, he will slowly learn what it means to truly "stay."
