The lyrics and music were produced by “__哇噻” (who is known to have done work for “The Voice of China”) with the collaboration of “OoopsMuK”. In the PV, Chen Ke is seen wearing several of her previous GNZ48 uniforms.
Although not an official GNZ48 release the song is supported by the group in a way similar to what was done for Lu Jing of Team NIII earlier this year. We covered that one here.
This appears to be the “year of the solos” for SNH48 Group as more and more solo singles get released (official or unofficial).
