妾相思君以忘
[qiè xiāng sī jūn yĭ wàng]
'A Concubine Thinks Fondly of You But Forgets You.' In ancient China, 'Qie' is how concubines called themselves before men. Thus this nickname represents someone who has forgotten a person but sometimes thinks fondly of him/her with a tone that's filled with melancholy and reminiscence.
