When the cold cage imprisons the moonlight, only the deep-rooted bond can split the darkness.
Ji Yuechen, known as the "Piano Elf", pawned himself to Yunze Haotian, the "living king of hell" in the business world, in order to save his family from being broken up. A cold contract imprisoned him in a golden cage. Yunze Haotian controls everything about him, appreciates his beauty, and is obsessed with the sound of his piano, but he is stingy with a trace of warmth. Beneath Ji Yuechen's meek appearance is an undercurrent of humiliation and unyielding stubbornness.
He played the piano, and silent resistance flowed from his fingertips; he obeyed, with broken stars buried deep in his eyes. Yunze Haotian was unexpectedly soothed by the sound of his piano, but his out-of-control possessiveness hurt him even more. The dusty childhood memories unexpectedly surfaced - it turned out that Ji Yuechen was the only little moon that gave him warmth in Yunze Haotian's dark childhood.
Love and hate are entangled like thorns. When a deadly conspiracy strikes, Ji Yuechen becomes the target of public criticism. At the critical moment of life and death, Yunze Haotian came to protect him with his life, bathed in blood. Seeing the man who had imprisoned him fall for him, the wall in Ji Yuechen's heart suddenly collapsed.
From the canary to the sidekick, from the cage to the way home. Ji Yuechen used the piano as a blade and went to the center of the storm with his lover. When the dust settled, he returned to the glorious stage with a song "Bright Moon", played only for the tyrant who learned to be gentle and respectful.
He is his only salvation, and he is his final return.
The prison heart of the overlord is finally tamed by the moonlight; the canary feathers can also tear the sky apart.
An ultimate love that begins with robbery and finally ends with soul-to-soul harmony.
