忘不掉一段旧情离不开一个旧人
[wàng bù diào yī duàn jiù qíng lí bù kāi yī gè jiù rén]
'Can't forget an old love, can't let go of the person I loved.' It expresses the deep nostalgia and inability to move forward emotionally from a past relationship. It suggests lingering attachment and unresolved feelings for someone from the past.
