我披上了婚纱新郎却不是他我穿上了西装新娘却不是他
[wŏ pī shàng le hūn shā xīn láng què bù shì tā wŏ chuān shàng le xī zhuāng xīn niáng què bù shì tā]
It literally reads 'I wore a wedding dress, but the groom was not him; I wore a suit, but the bride was not her'. This deeply sorrowful expression shows regret and unrequited love where despite the attempts of marriage, the true partner wasn't there.
