Lin Hong is a surveyor. His job is to use instruments to measure cities, accurate to millimeters. But at the age of 29, he can't predict people's hearts - because of the shadow of his childhood, he is always uneasy in love and is afraid of being left behind, so he works hard just to prove that he is "useful".
Lu Zhi is a keyboard player, 24 years old, talented and radiant on the stage. But no one knows that there is an island in his heart. His parents' incomprehension made him accustomed to hiding his true feelings. The more he liked him, the more he had to push him away, testing the other person's bottom line by being hot and cold.
In 2025, in Ningcheng, a small northern city, an old factory building is about to be demolished. The surveyor met the keyboardist playing an abandoned piano. He gave him the most accurate architectural data, and he played him an improvised melody in the sound of rain.
One is eager to use "being needed" to tie the relationship, but the other always runs away subconsciously when the other person approaches. This love is like a difficult pas de deux - I take one step forward, you take two steps back; I muster up the courage to get closer, but you close the door.
They are attracted by the resonance of each other's souls, and hurt each other by their respective psychological scars. This is a long healing journey: about how two people with "flaws" learn to no longer act perfect in love and how to embrace each other's true and fragile nature.
When the old factory finally turned into a park, and when the surveying drawings met the music melody, they understood: love is not about precise measurement, but about allowing errors to exist. The most beautiful chords are often composed of less-than-perfect notes.
"Measuring the distance between heartbreak and psychology, it's about one light year."
"Lu Zhi, I can never measure your notes accurately."
