Their love line is distinct and stems from that encounter ......
Xiaolun is dependent on her father. Her father was a music teacher at Tamkang Arts High School, and Xiao Lun was nurtured by him since she was a child, possessing extraordinary musical talent. On his first day at Tamkang Arts High School, When he visited the campus, he was attracted by a mysterious piece of piano music. He is led by the sound of the piano and enters a 100-year-old piano room. He realizes that the piano player is a beautiful girl named Xiaoyu. The two of them do not talk to each other, but when they look at each other, both of them have a subtle feeling.
Xiaoyu was in Xiao Lun's class, and because she was always late for class, she was often forced to sit with Xiao Lun in the back row. The relationship between the two has grown rapidly. But whenever Xiao Lun asked about the mysterious music he heard in the piano room that day, Xiao Yu always answered ambiguously, "That's a secret that can't be told. ......" A love affair full of romantic suspense began from then on... ...?
In the end, he realized that Xiaoyu and him are not from the same era, they are exactly 20 years apart. Xiaoyu was also a student of Xiaolun's father. When Xiaoyu was a student.
There was another girl in Xiao Lun's class who liked Xiao Lun. But only Xiao Lun could see Xiao Yu. One night, Xiao Lun asked Xiao Yu to meet him at the piano room, but Haruyi (the girl who likes Xiao Lun) arrived first. Lun closes his eyes and thinks it's Xiao Yu, so he asks her to kiss him. Unfortunately, Xiaoyu saw her, and she thought that Xiaolun had fallen in love with her. She was so angry that she didn't go to school for a few days.
When Xiaolun was with Xiaoyu, he once said to Xiaoyu, "I'm going to play a piece of music especially for you at the graduation ceremony". When it was time for Xiaoyu to graduate, Xiao Lun's father came to Xiaoyu's home to look for her, hoping that she would be able to attend the graduation ceremony. Xiaoyu remembered what Xiao Lun had said. After taking a picture with Xiao Lun's father, she went to the piano class again. After playing <Secret> again, she arrived at Ren's graduation ceremony 20 years later. She heard Ren play <Swan> for her. At that moment, on the stage, Xiao Lun finds Xiao Yu, whom he has been searching for 5 months. When Xiao Yu saw Xiao Lun looking at her, she ran away. Xiao Lun hadn't finished playing the piano yet, so he ran after Xiao Yu. Xiao Lun caught up with her and hugged her. (Xiao Yu was running slowly because she had asthma.) He said to her, "Promise me you won't disappear again." Xiao Lun's father also chased after her and scolded him to keep playing. Xiao Lun turned around and asked Xiao Yu to wait for him in the classroom. When he turned around, Xiao Yu saw the lucky bracelet that Qing Yi lent to Xiao Lun. Xiao Yu thought that Xiao Lun had been lying to her. It's 20 years later.
