月老肯定玩断了我的红绳
[yuè lăo kĕn dìng wán duàn le wŏ de hóng shéng]
'The matchmaker god must have broken my red thread' alludes to Chinese mythology where 'matchmaking god' ties people's feet with an invisible red thread as destiny. If this thread is broken, it could mean that fate or romance seems to fail.
