我跪下你也未必爱我
[wŏ guì xià nĭ yĕ wèi bì ài wŏ]
Translates to 'Even if I kneel down for you, you might not love me’. This conveys the despair of feeling unwanted or undervalued no matter how far one goes or sacrifices. It indicates strong but unreciprocated emotions and a plea that often fails in seeking acceptance or affection in return.
