你的剧本我只是观众
[nĭ de jù bĕn wŏ zhĭ shì guān zhòng]
The statement means 'I am just a spectator of your play', implying emotional or relational distance, possibly after giving up or losing interest. The person is no longer involved but remains aware of events happening yet chooses not to be active, like watching a drama unfold rather than performing it.
