Su Wan thought that her singing would only be sung to the moonlight in the middle of the night.
As the most inconspicuous "invisible person" in the Conservatory of Music, she has a heavenly voice and an absolute sense of pitch, but she doesn't even dare to raise her head during class presentations. Until that rainy night, she secretly played and sang original ballads in the piano room, and was heard by Lu Zhiye who was hiding outside the door - the great composer who was brilliant on the stage but as cold as ice in private.
"Your voice is the melody I have been looking for for a long time."
Lu Zhiye's intrusion shattered Su Wan's inferiority complex like a beam of light. He took her out of the piano room and taught her to speak under the spotlight; she used her clean and pure singing voice to heal the impetuousness and confusion in his creation.
Some people laughed at her for not being worthy of the favored one, but he composed her original song into a hit song, and the whole network declared: "All my melodies are only born for her voice."
Some people questioned him for hyping up his relationship, but she responded with a song "Heartbeat Frequency" at a concert with thousands of people: "His rhythm is the same as mine."
From the campus piano room to the stage with thousands of people, from secret crush to two-way love, they use music to write love and use companionship to heal the past. It turns out that the best love is when you understand my melody, I love your heartbeat, and we become better together.
