This translation prioritizes three things the original hinges on: the emotional arc from confession to renewed devotion, the register — formal, self-lacerating, then suddenly tender — and the sonnet's musicality, built on Shakespeare's iambic pentameter and tight rhyme scheme (ABAB CDCD EFEF GG).
I chose a modern Chinese register deliberately: its syntax sits closer to English than classical or archaic Chinese does, which made it possible to preserve the sonnet's fluency and pacing rather than fragmenting it into a more compressed, classical cadence. That modern register still carries its own rhythm — occasional rhyme, and a recurring four-character cadence, so that readers can more readily sense the acoustic beauty the sonnet form was built for.
