In Jiangcheng, where the rainy season lasts, seventeen-year-old Lin Wan is trapped in a leaky roof and rusty family ties. She hid her humble dreams in the piggy bank and tucked the girl's thoughts into the 53rd page of the piano score. Until Zhou Weiwei's sweet lies were like a poisoned knife, Chen Yu's understatement of "backup" crushed all her fantasies, and her mother's words of "for this family" made her sacrifice the remaining dignity with her own hands - a blood-stained five-cent coin, which became a cold shackle around her neck.
When she fell like a glass bird on the edge of an abandoned high-rise building and crashed into the cold corners of fate, the flying fragments and warm blood reflected Chen Yu's tears of panic that he had never seen before, and a twisted musical note necklace stained with the blood of two people.
Lies will eventually be broken, but under the solidified blood, is the truth enough to become wings?
How could a bird whose bones were corroded by rust pick up the fragments of glass that had cut her in the mess and let out its first hoarse cry toward death?
Concept: Youth is broken by cold rust (the pain of the original family) and sharp edges (class bullying). But when the girl crashed into the glass curtain wall of fate on the edge of destruction, the flying bloody fragments tempered the power to live towards death - using scars as medals, picking up the remains of lies, and sending out a hoarse but true "rusty bird's first cry" to the world.
