余生与你与你余生
[yú shēng yŭ nĭ yŭ nĭ yú shēng]
'Rest of Life With You' is repeated twice for emphasis. It conveys strong emotion - deep love or companionship. Repeating emphasizes how important 'you' is in their future life - they want to spend every moment together with the loved one(s), making the sentiment especially touching and romantic.
