如果不爱你又怎会在乎你
[rú guŏ bù ài nĭ yòu zĕn huì zài hū nĭ]
The meaning is similar to 'If I didn't love you, why would I care about you?' This conveys deep caring and love. It shows the complexity in expressing feelings toward someone - the struggle with affection and care and the way people often notice and cherish each other only because of love.
