我不姓李我不在你心里
[wŏ bù xìng lĭ wŏ bù zài nĭ xīn lĭ]
This means 'I don’t have the last name Li, nor do I exist in your heart/mind.' This reflects disappointment, indicating that someone doesn’t hold a significant place in another person’s thoughts or affections. It carries a melancholic tone and suggests a lack of recognition or importance in another’s life.
