Amid the chirping of cicadas in midsummer, Xu Qinghe met Cheng Ye for the first time. The boy was smiling in the sunshine, but she just wanted to hide in the shadows. The small town where she teaches is full of wild flowers, and there are also secrets that she dare not tell. When Xu Qinghe plucked up the courage to stuff the diary filled with thoughts into Cheng Ye's schoolbag, he saw Zhou Kexin holding his arm affectionately. A misunderstanding, a sudden heavy rain, all the throbbing was washed away beyond recognition. Song Zhi's urging, Zhao Yiming's chaotic assist, and Chen Mo's words "Teacher, brave people will shine" made Xu Qinghe decide to let go of everything and say to Cheng Ye the words that had been hidden throughout the whole summer at the last bonfire party.
