Yu Boya, who was the best in the south of the Yangtze River in piano skills, was lonely and cold-tempered. He used the piano as a sword and music as a prison.
Zhong Ziqi, the dandy son of the Zhong family, hides behind his mask a delicate heart that can hear the music of the world.
During a bet, Ziqi accidentally entered the Qingyin Pavilion and revealed the deep loneliness hidden in Boya Qin with one sentence.
"What you are playing is not an empty mountain, but a mountain waiting for people to come."
From that moment on, Boya knew that the soulmate he had been waiting for half his life was here.
He used the sound of the piano as bait and every step of the way, luring Ziqi into a carefully woven web of love.
Ziqi went from admiration to addiction to fear - he found that he could no longer live without Boya's piano, let alone the person who played it.
"Bo Ya, are you my soulmate or my inner demon?"
"Is there any difference? A close friend is meant to live in the heart."
A broken string becomes an alliance, and a golden ring locks the heart.
This unparalleled love for a bosom friend grows wildly in control and dependence, pain and sweetness.
Purpose: To explore the depth and complexity of the "bosom friend" relationship: when pure artistic resonance evolves into a profound bond, how to find a mutual balance between control and freedom, pain and redemption, and ultimately achieve individual growth and emotional sublimation.
