Lin Tang, a sophomore at the Conservatory of Music, unexpectedly wins the favor of Chen Jingfei, but after stepping into the exclusive piano room, he discovers that this is just a trap carefully designed by the talented musician. From private guidance to public humiliation, Chen Jingfei used the name of art to mentally tame Lin Tang, weaving a cage called "perfection" on the black and white piano keys. As the butterfly's specimen-like control gradually escalates, Lin Tang catches a glimpse of the truth about Chen Jingfei's morbid obsession between resistance and addiction. A deliberately created stage accident pushed this twisted teacher-student relationship to an irreversible conclusion.
