[Two male protagonists + bamboo horse + redemption + reunion]
Ten years ago, Xia Zhi'an and Gu Yang became familiar with each other during the summer.
From then on, the sensitive and lonely Xia Zhi'an began to gradually cling to this "brother" who was two months younger than herself.
They walk together, go shopping together, study together, and climb mountains together.
Just when Xia Zhi'an felt that he and Gu Yang would be together forever, Gu Yang left him in the summer, and the two had little contact from then on.
When Xia Zhi'an was twenty-five years old, she met Gu Yang again in the summer in a small town. The star that the boy had hidden five years ago gradually became brighter.
