The story began in the spring 20 years ago. Twenty years ago, the world-famous pianist Yuki Morishita (played by Misato Tanaka) came to Nanfengyuan Island from Tokyo to attend a piano concert. Ryuji Nakamura (Kuranosuke Sasaki), a fisherman, was deeply moved by her wonderful performance, and she recovered the gem coral known as "the symbol of female guardian" from the bottom of the sea. Two lovers named their daughter Liang Zi. Unexpectedly, soon, the disease was taken away from Dragon and Liang Zi by a screwdriver.
Born in the same year, Liang Zi, Jing Daole and Uehara Kazuyoshi (played by Shinji Rachi) grew up like brothers. However, when it came to deciding their own lives, the three men chose different paths. One of them also decided to stay on the island. Big sister is eager to enter the art university in Naha, while Liang Zi wants to be a nurse and plans to leave the island. In the spring when they were 18 years old, they also presented a love song "Tubarama" to Liang Zi, which completely changed the relationship between the three people. That night, Liang Zi and Ye Yi's hearts clung together, and she decided to stay on the island. Jing Daole, who has a crush on Liang Zi, was at a loss and left the island ahead of schedule. Yi also planned to marry Yu, but was opposed by Long Er. He heard that Long Er once used a screwdriver to dive into the seabed for his lover to collect precious corals, so Yi also wanted to find precious corals for his lover in the sea. A few days later, suddenly came the news that a man was drowning. Liang Zi couldn't accept this reality, had a nervous breakdown and was sent to the hospital. Liang Zi has never left her mother's piano since she left the hospital. Every evening, she ran aimlessly to the beach, not talking to anyone, but living in memories.
A year later, Jing Daole returned to his hometown in the name of independently completing the island's traditional pottery. In fact, his heart still cares about Liang Zi. At the seaside, Jing Daole and Liang Zi met again by chance. Liang Zi, whom I haven't seen for a long time, stopped smiling. One day, when the elder sister was standing near Long's house, she saw an unexpected scene-the keyboard of the piano was badly damaged and all the strings were cut off. Big sister was surprised and asked Long Er what was going on. Long Er said that he cut the string on his own initiative. Liang Zi, who was discharged from the hospital, has been playing the piano, which has affected the lives of other residents on the island. No matter how much Jing Daole wanted to save Liang Zi and Longji from their sad memories, he found that there was nothing he could do, so he had to make pottery day and night. Seeing such hard work, Liang Zi has undergone slight changes. She started making vases and sent them to Ye Yi's house with her elder sister. This is the first time that Liang Zi walked into Ye Yi's room. In Aiya's room, there is a photo of Liang Zi who is full of energy. Liang Zi hasn't appeared since he lost Yiya. Looking at Liang Zi wandering in the abyss of despair, Jing Daole suddenly made up his mind that he would dive into the bottom of the sea to find precious corals. Who knows, Jing Daole, like Ayi, went there and there was no news. After learning the news of Jing Daole's disappearance, Long Er immediately went out to sea to look for it.
