我要让情敌当伴娘
[wŏ yào ràng qíng dí dāng bàn niáng]
It suggests humorously the victory over love rivalries. By letting your 'rival' play a subordinate or supportive role during one's wedding day, this name shows the triumph in competition, with an implied bit of triumph over adversaries. Notably, this might carry some sarcasm or irony, indicating unresolved tension.
