笨蛋你可知道有个傻瓜爱你
[bèn dàn nĭ kĕ zhī dào yŏu gè shă guā ài nĭ]
Translates to 'dumbass, do you know there is a fool loving you', expressing endearment from a silly perspective. The seemingly negative 'stupid' actually reveals a simple, pure, loyal and persistent love which doesn't care about whether others understand it.
