她是我挥之不去得影子
[tā shì wŏ huī zhī bù qù dé yĭng zi]
This conveys a person who can’t forget someone no matter what, even wanting to get rid of such memories - that past remains as persistent as the shadow cast by oneself. The memory of her always haunts or lingers within oneself, symbolizing lingering affection, longing, guilt, or unresolved issues.
