爱过后才发现我爱的不是你
[ài guò hòu cái fā xiàn wŏ ài de bù shì nĭ]
'Realized I Didn't Love You After All, Even though I Thought I Did' captures heartbreak after love; acknowledging that one’s previous feeling towards another was mistaken or misidentified. It reflects regret and disappointment once true emotions come to light.
