打雷了下雨了我不爱你了
[dă léi le xià yŭ le wŏ bù ài nĭ le]
It's poetic but cynical, using weather changes as metaphors. It suggests that feelings are fleeting just like sudden natural events: When thunder strikes and it rains, the feeling or relationship also comes to a quick end. It's a creative, slightly whimsical way to express an abrupt shift away from love.
