浅唱这份情淡唱那份爱
[qiăn chàng zhè fèn qíng dàn chàng nèi fèn ài]
This suggests lightly humming this affection and that love. Here '轻唱' ('lightly singing') conveys feelings of tenderness with both affection and a more profound love, often expressing bittersweet emotions where the past has left a mix of nostalgia and loss.
