我需要你就像心脏需要跳动
[wŏ xū yào nĭ jiù xiàng xīn zàng xū yào tiào dòng]
'I need you as much as my heart needs to beat' conveys a deep emotional dependency or affection towards someone. It’s a poetic expression of essential love or connection, suggesting that this person is as necessary for one’s well-being as breathing itself.
