An infinite cycle of time begins, and a new kind of space called the "School" appears.
Poor Qi Mo, a third-year senior student repeating the college entrance exam, is forced to enroll once again, but can only become a freshman.
Here, there is none of the treachery, volatility, or schemes one might expect.
Instead, there are endless major and minor exams, midterms and finals; a homeroom teacher tearing out their hair because they can never find the freshmen they are looking for; and a class fund that is almost empty.
But the School’s oddities go far beyond that. Perhaps in a corner of one of the instances, or in the gaps between repeated cycles, there will always be an unexpected encounter, a reunion that takes you by surprise.
In short, at the School, may all students study hard and improve every day, and live up to their teachers’ expectations.
Theme: Study hard, improve every day, and cherish life, starting with yourself.
