我说我爱你你信了会死吗
[wŏ shuō wŏ ài nĭ nĭ xìn le huì sĭ ma]
A passionate expression of intense feeling with a touch of desperation, questioning whether one should believe in a declared strong love. Literally, 'if I say I love you, would you die from believing it?'. This shows how serious or deeply felt the expressed emotion is.
