What are the poems that describe "the one who loves most will never understand himself"?

Ren Yue Song

What a night tonight, roaming in the river.

What day is today? Together with the prince.

I'm ashamed. I don't deserve my humble opinion.

My heart is stubborn and uneasy, and I know the prince.

There are trees on the mountain and branches on the tree. My heart likes you. You don't know that.

Brief introduction of Yue People's Song;

Ren Yue Ge, together with other folk poems of Chu, became the artistic source of China's earliest translation of Chu Ci, which reflected the harmonious coexistence of people of all ethnic groups and expressed cross-class love. Its ancient Vietnamese pronunciation was recorded in Shuo Yuan written by Liu Xiang in Han Dynasty.
