The characters in this book are all eccentric in the eyes of others. They don’t stick to their regular jobs, dare to love and hate, are passionate, fragile, and lonely, living like outliers in this realistic society. The most common thing they do is suddenly explode when you least expect it, giving you a heartfelt blow to your life philosophy. The most mischievous friend became a teacher, the usually honest classmate became a hooligan, and the flirtatious female senior became a full-time mother… Each of them has lived vigorously in this world, colliding with the passionate world with their own passion. No matter how many years have passed, I can still clearly remember their faces. Youth never fades, it just gradually fades away.
