Looking for a Japanese anime title

"Hearing the Waves" uses the voice of a college student, Du Qituo, to recall his middle school days. The director prefers to use flashbacks and flashbacks in his memories, making the memories overlap and overlap. But it's not psychedelic, it's just more inexplicably exciting. The film begins with Taku Tuzaki, who was admitted to the University of Tokyo, returning to his hometown of Kochi, a small seaside town, for the first time, and remembering two people in high school - his friend Yutaka Matsuno and his female classmate Rikako Muto. The story is divided into two threads: friendship and first love, which are both divergent and intertwined. The first time Du Qi and Matsuno spoke was in junior high school. Because the school unilaterally canceled the students' spring trip due to performance issues, the students were indignant. However, the only ones who bravely stood up and expressed their "objections" were Du Qi and Matsuno, another classmate whom he did not know. On that day, the school arranged for the two of them to write down their names and opinions in the art room. Two teenagers were sitting at the window, imagining how they would look back on today ten or twenty years from now. At this time, the clouds on the horizon outside the window were changing, like unknown events in the world. Later in the film, Du Qi, who has entered university, comes back from Tokyo and walks with Matsuno on the pier. Talking about yesterday, the screen gradually shows the boundless sea and sky, and the beautiful trumpet sound in the background is filled with thoughts and past events - this This is one of the most touching parts of the film. The friendship between the two teenagers is connected from beginning to end and forms a circle. There are blends, suspicions, and breaks in the middle. These mottled moments combine to form an unforgettable period of youth. The first time Du Qi and Muto spoke was during their high school spring trip to Hawaii. Muto wanted to raise money to visit his father in Tokyo, so he pretended to have lost the money and borrowed money from Du Qi. As a result, Du Qi was forced to accompany Mu Teng to Tokyo. The two spent the night together in a Tokyo hotel in a daze, and Du Qi slept in the bathtub consciously. In Tokyo, Du Qi saw the weak and everyday side of Muto, who was cold, arrogant and outstanding in everything in Kochi, like a "real girl". After returning to Kochi, Muto returned to his original cold arrogance. Later, due to Muto's rude words to Matsuno, who had a crush on him, Du Qi and Muto became enemies. However, at the class reunion a year later, Du Qi learned that Muto secretly admitted to a university in Tokyo despite his mother's opposition. When someone asked her why, she said there was someone she wanted to see in Tokyo. When asked who she was, she said it was the person sleeping in the bathtub. Only then did Du Qi realize that Mu Teng had always had love for him, but he was unaware of it. When she heard someone say that she likes "people who sleep in bathtubs", the few moments that Du Qi had with Muto in the past were suddenly brought to mind. The screen was intercut with several flashback scenes and Kochi's. In the night scene, outside the painting are the words she once said to him. At this time, not only the characters in the play looking up at the lights in the mountains, but also the viewers in front of the screen must have been emotionally agitated. The title "Hearing the Waves" presumably refers to the "sound of waves in our hearts" we hear at this time. At the end, Du Qi finally reunited with Muto on the platform, and the waves in his heart started again. However, at this time, the two of them did not have any dialogue, only their eyes intertwined, allowing us to use our best imagination to fill their future. Years...
