我们背对背拥抱来用沉默在咆哮
[wŏ men bèi duì bèi yōng bào lái yòng chén mò zài páo xiào]
'We hug back-to-back while silence roars between us' suggests a complex relationship where both parties try to stay close yet cannot communicate openly; instead, their unspoken words and emotions become powerful voices through silence.
