If you ask Tang Yuke when he most wants to go back, he would like to go back to the three years of high school, the sweetest, stupidest and most regretful days. He didn't have time to work hard, he didn't have time to finish drawing the back of the front table from every angle, and he didn't have time to say "I like you" to Gao Jingyan.
Purpose: Remembering the people you missed
