爱情面前对不起算个毛线
[ài qíng miàn qián duì bù qĭ suàn gè máo xiàn]
A blunt and colloquial statement meaning 'in matters of love, apology doesn’t count for nothing (slang).' It suggests that in relationships, mere apologies aren’t adequate if true respect and effort aren't given. It reflects on the insignificance or powerlessness of saying sorry in certain contexts.
