忘记曾经受过de殇
[wàng jì céng jīng shòu guò de shāng]
This username implies someone who is trying to move on from past wounds or sadness. 'de' is used here as a romanization of the Chinese character 得, which serves grammatically to connect different parts of speech, though it's somewhat incorrectly used in place of 的, leading to expressing possession.
