Briefly introduce the story of love summer at 38℃ with the taste of that summer.

Their story begins in a warm summer, when the pulse is beating fast. Hiro (Hu Yuwei), Sandworm (Jay Chou) and Jing Li (Yuan Xinyu) grew up together in Kinmen, but Hiro experienced the first difficulty in his life when he graduated from primary school: Li Jing of the trio went to Xiamen to fight for a career with his father, and Xiaoqing (ghost Emma Wu), a girl who met by Xiaobu Dance, quietly moved to Taipei, while Hiro's father was sent to Taiwan Province Province by a winery for a year, and his mother was never heard from.

Honghe helps his mother, Sandworm, run a homestay in Jinmen, and Hong also serves as an ecological tour guide. With his father's career, Li Jing once again returned to this land where Hiro had been missing for many years. The piano girl Xiaoqing was invited to perform at the opening concert of Golden Gate Hotel. Xu Lei (Wang Rui), the designer of Grand Hotel, will also attend the opening ceremony. All the parallel lines intersect again, and the meeting of five young people is like the arrangement of notes on the music score, and the melody of love quietly rings.

The relationship between Xiaoqing and Hong has been tense for many times because of misunderstanding, but they are also closer to each other because of these realities and coincidences. Xiaoqing frankly admitted her mistake and acted bravely, and gradually became lovely in Hiro's eyes. Hiro's stubborn choice of kindness and cautious communication with people made Xiaoqing feel more sincere. Two people look at each other and attract each other in the ambiguous throbbing air.

Despite her mother's opposition, Li Jing launched a plan to pursue love ten years later. Looking at Xiaoqing and Hong getting closer, her yearning for love can only be forwarded to the sound of the piano flowing at her fingertips. Ten years later, the guardian knight Sandworm can only do everything possible to attract the attention of Princess Excavate.

Xiaoqing's frankness and naturalness attracted Xu Lei. On the way of brewing love sorghum wine, he dabbled deeply but didn't master the real trick.

When the dream love bus starts, people who get on it can't turn back.

The Xiamen Station of Piano Island-Gulangyu Island has begun to change: the secret of the coincidence of the previous generation, the regret of the impulse of the insects, and the real reason for Hiro's retreat from love. ...

One by one, a group of young people were confused and at a loss. Then, the next summer came again.

According to the agreement, Xiaoqing returned to Kinmen! Same face, same smile, same minuet in G major. When Hong thought that everything had come to a successful conclusion, A Huibo (Mao Bo) hinted that he would go to the most beautiful back hill, where he could see the blue sky and sea of Kinmen, and there was a final and sad answer waiting for him ... They fell in love with the fateful meeting this summer.
