Does anyone know the original name of the song "Little Enemy" adapted by Zhao Wei in Deep Rain?

Zhao Wei, who plays the little girl in the play, not only sang the opening song Deep Rain, but also included the ending songs Farewell to the Station, Involuntary, Misty Rain, as well as the interludes Little Companion, Since Parting, New Lanhuahua and Flying Waltz. Due to the needs of TV series, most of the songs have a strong Shanghai flavor, and most of the lyrics are written by Qiong Yao. In addition, these songs have also been adapted into orchestral music, so that fans can feel the twists and turns in the play while listening to the songs.
