There is a joke that includes my beloved concubine and me. It seems to be about weight. What is the original text?

Is it possible that a certain classmate’s deskmate was talking in his sleep during class: “My beloved, my dear, don’t leave me! I don’t want to lose you!”

That classmate was speechless. , I continued reading or something, but my deskmate burst out again: "I am not willing to accept it! I am not willing to accept that the Qing Dynasty was destroyed like this!"
