After failing in the high school entrance examination, Ai Junyi entered high school unwillingly, vowing to avenge her shame. In the panic at the beginning of the school year, she met Li Siyao and Xian Bowen, and through the twists and turns of military training, choir interviews, and student union elections, her fate quietly intertwined with Lu Hongyi's.
From Lu Hongyi's low-pitched "rap" teasing during the student union election, to the hair-pulling fights when looking for class discipline; from the pulling of borrowing badminton rackets and not borrowing, to the fright in the haunted house at the amusement park and the milk tea agreement on the subway line, the two gradually got closer through their youthful trials. Ai Junyi would secretly give him candy when he had low blood sugar, and would clumsily comfort her when she was wronged. Ai Junyi also felt distressed when he had a fever, and wrote down his every detail in countless memos.
However, youthful love is always accompanied by the pull of inferiority and pride. Faced with Lu Hongyi's confession, Ai Junyi used pickiness to cover up her panic because of her low self-esteem. She even decisively severed the relationship after a phone call full of grievances and accusations due to misunderstanding and anger.
When the shutter of the graduation photo was pressed, the two of them peeked at each other through the crowd. Those unspoken apologies and gratitude eventually turned into regrets in their hearts. If given another chance, would you still choose to be together? This is a youthful past about growth, trials and misses. All the joys and tears are finally condensed into one sentence: "I'm sorry, thank you, I loved you."
