我曾给你最温暖的拥抱你却给我最痛心的玩笑
[wŏ céng jĭ nĭ zuì wēn nuăn de yōng bào nĭ què jĭ wŏ zuì tòng xīn de wán xiào]
'I once gave you my warmest hug but you responded with the most heart-wrenching joke' - it implies that once they had close and genuine feelings, but instead of reciprocating the warmth, it was met with deceit or mockery.
