Ning Yun always went to the empty music classroom in the old teaching building on cloudy days. There was an out-of-tune upright piano, and someone who shouldn't be there.
Li Shimu is a rumored piano genius and the grandson of Xiao Sai Silver Medal, but he never shows up at school. That afternoon, she opened the door and heard him playing an old song. Her student ID card slipped out of her pocket and dropped beside the piano bench. He picked it up and saw her name.
A love triangle began from then on. Ning Yun has a boyfriend, Feng Suyuan, whose possessive and controlling nature makes him unable to tolerate her getting close to others. Han Zhirui was Li Shimu's childhood sweetheart. She had watched him grow up and knew that he had changed recently - he started playing pop music and began to care about another girl. Four people, four relationships with their own concerns, interfere with each other in the same song. Some people want to get closer but are timid, some want to withdraw but are unwilling, some want to hold on but can only watch what is in their fingers slipping away little by little.
Concept: About those "displaced" moments in youth - when you fall in love with someone, he is looking elsewhere; when he finally looks at you, you are already gone. Four people in the same song, but never on the same beat. What the work wants to explore is: there is no right or wrong in love itself, but if love occurs in different time zones, someone is destined to miss it. Music is a metaphor for connection and dislocation. Those keys that are pressed in the piano room on a cloudy day will eventually echo in someone's heart for a long time - even if they are never heard by the other person.
