若不久伴便久绊若不深爱便深碍
[ruò bù jiŭ bàn biàn jiŭ bàn ruò bù shēn ài biàn shēn ài]
'If not a long companion then an enduring entanglement, if not profoundly in love then deeply troubled' implies a profound reflection on relationships - that is, either becoming intimate friends who have shared experiences for a lifetime or getting into conflicts; either falling deeply in love or causing great disturbances to each other. The author expresses the complex emotional connections that individuals can share with another through these interwoven sentences.
