2011 11 11 Is the Day of the Holy Stick, a day when countless people are sad and happy. The three pairs of protagonists in the book are written in storyboards. They are in junior high school, high school and college. They all broke up after watching a movie together on 2011 11 11. It is heartbreaking.
Pure love in junior high school will always be disturbed by a group of people who think about "you". Don't fall in love in junior high school because you can't bear the pressure.
Deep love in high school is always overwhelmed by teachers' studies. Don't fall in love when you are 16, because that person is the person you love most in your life.
Romantic love in college is always broken up by the catastrophe of graduation. Don't fall in love in college, because people are too unprofessional.
