How can we call it youth if we are not crazy? When Ju Ran (played by Dong Zijian) took graduation photos before the college entrance examination, he loudly confessed his love to Huang Jingjing (played by An Yuexi) who he had been secretly in love with for three years in front of all the teachers and students in the school with Tagore's poems, and harvested a sweet first love. But soon the sweetness of first love was destroyed by his mother (played by Yongmei) who came after hearing the news. Huang Jingjing left proudly under the stimulation of Ju Ran's mother. Ju Ran was sad and wanted to climb the wall to save his first love, but he broke his tailbone. He failed the college entrance examination after being brokenhearted and injured. Seeing Huang Jingjing going to Fudan, he decided to repeat his studies and pursue love. He began a crazy senior high school journey. In every youthful memory, there is a girl who is deeply in love and silently pays, a few emotionally rich and loyal buddies, a group of friends with their own stories and characteristics, and a memory shared by everyone. This is the youth school-a period of time that is always flashing in life and never fades.
