Shen Yao, an aloof academic who is passionate about cryptography, develops feelings for the quirky Yu Luyao beyond friendship in high school. Yu Luyao's mother has been worried about her future marriage since she was a child because of the fortune teller's words. After graduating from high school, the male protagonist gave up his dream and chose to serve the motherland. The girl chose foreign aid and medical treatment. In fact, she never knew that Shen Yao chose this industry for her and went to the front line for him, until a netizen who had known Yu Luyao for 7 years, Dazzling Xiaolu, disappeared overnight and was never seen again.
