我要让情敌当伴娘我要让情敌当伴郎
[wŏ yào ràng qíng dí dāng bàn niáng wŏ yào ràng qíng dí dāng bàn láng]
It translates to 'I want to make my rival in love to be the bridesmaid / groomsman'. This represents a humorous, sometimes vengeful intention against a romantic rival - wanting to assert one's superiority by placing them in a position where they can visibly see the happy couple during important moments like a wedding.
