暧昧散尽笙歌婉转
[ài mèi sàn jĭn shēng gē wăn zhuăn]
It suggests that after all the ambiguity (in terms of feelings) has dissipated between people, the music is gentle and soothing. '暧昧' (ambiguous/unclear feelings), indicates a phase where feelings are uncertain; '笙歌婉转' refers to melodious flute-like songs, symbolizing peace, clarity after confusion, or moving on from an ambiguous state to stability.
