我只是你和她电影中的过客
[wŏ zhĭ shì nĭ hé tā diàn yĭng zhōng de guò kè]
This user name, 'I am just a passerby in the movie between you and her', reflects a sense of detachment or unimportance felt by the user. There's an underlying sadness in the context, like someone feeling peripheral in other people's stories or lives. The 'movie' implies events in real life that involve two important characters ('you and her'), but to this individual, he's insignificant.
