我到底爱你什么人渣
[wŏ dào dĭ ài nĭ shén me rén zhā]
'What did I love in you, scum?' It conveys regret, disillusionment, or frustration with love experiences. Possibly describing feelings toward a relationship with someone who has been hurtful. The use of 'scum' highlights a bitter tone in this self-reflection.
