唯他一生爱她一世
[wéi tā yī shēng ài tā yī shì]
'Wei Ta Yi Sheng Ai Ta Yi Shi' means 'He loves her only once in his lifetime.' In this context, the Chinese character 'only' implies exclusiveness, suggesting that such love will never again be found in his life except from her. It conveys feelings of deep, monogamous romantic attachment.
