怪我孤陋寡闻不知你心有人
[guài wŏ gū lòu guă wén bù zhī nĭ xīn yŏu rén]
'Blame Me for Ignorance, Unaware of Your Affections' admits one's lack of awareness regarding someone else's relationships. It shows self-criticism and acknowledges that due to ignorance or oversight, the person was unaware of the love in the other's heart.
