When she was sixteen years old, Zhao Yining, a repeat student, was afraid of two things every day: one was the unsolvable final question on the math paper, and the other was the boy riding a bicycle in front of her on the way to school.
His name is Gu Changan, he is first in grade and walks very lightly. No one knows the reason why he dropped out of high school to repeat his studies. She followed him on the road - starting from the junior high school in the town, passing through rice fields and canals, and branching at a fork in the road, she went left and he went right. I don't know from which day, this twenty minutes together became the thing she looked forward to the most in the day, and he would wait for her in the carport every night, like a street light that would never be late.
Later, from a rural road without street lights, they were admitted to the County No. 1 Middle School together, and then went to Shanghai together, and then ran to further places. This is not only a story about first love, but the entire process of two teenagers walking side by side for sixteen years, from "the same road" to "the same destination".
