话题都关于他话题离不开她
[huà tí dōu guān yú tā huà tí lí bù kāi tā]
This nickname expresses someone always being surrounded by conversations centered around certain individuals, either 'him' and/or 'her', reflecting a preoccupation or perhaps annoyance at how specific people consistently feature prominently in everyday discussions. There’s often underlying sadness and envy about this situation.
