丧服观你婚礼喜服看你分离
[sāng fú guān nĭ hūn lĭ xĭ fú kàn nĭ fēn lí]
The netizen implies a very bitter and dramatic love story: Wearing mourning clothes to attend the former lover's wedding in grief, but ironically having to wear bridal clothes later to see this marriage end sadly. It reflects a broken relationship filled with irony and sadness.
