The beacon smoke on the border of Yong'an Kingdom and the wind and moon in the capital are intertwined into poetry in the lives of the two people.
She was Chu Zhao, the general who held the country with his silver armor stained with blood and his sword pointed at the northern frontier. She was decisive in killing on the battlefield, but there was an unknown softness in her eyes. He is Su Lingding, a cold piano player trapped in a red building. "Qing Xin Yin" is flowing from his fingertips, and the expectation for freedom is locked between his brows.
An accidental listening to the piano made the iron-blooded general heartbroken by the purity behind the music. When criticism in the court and frame-ups by love rivals followed one after another, Chu Zhao wielded his sword to protect him and shattered the worldly prejudices with the promise of "keeping it at the top of his heart". Beidi was not in peace, and she had to go to the battlefield again, so she gave him a jade pendant as a gift to allow him a return date. In the loneliness of the house, he guarded the letters and music scores, waiting for her to return from the smoke.
From the redemption at the Red Mansion to the mutual care at the General's Mansion, from concerns at the border to requests from the court, they transcended the differences in their identities and wrote about their deep love for each other in troubled times. When Chu Zhao defeated Beidi and granted him the title of King of Zhenbei, the empress personally gave him a wedding ceremony, with red makeup and armor matching each other, and it eventually became the most touching legend in the capital.
This is a love song between a general and a piano player, which hides the concern in the flames of war and the perfection in the prosperous age.
