你是氧气却能让我窒息
[nĭ shì yăng qì què néng ràng wŏ zhì xī]
'You Are Oxygen Yet Suffocating Me': A paradoxical situation where something essential becomes too overwhelming - similar to saying 'too much love hurts'. Despite oxygen being necessary for survival, the metaphor extends to a partner being so intense that instead of helping, they start suffocating another individual.
