疯子只爱你的疯子傻子只疼你的傻子
[fēng zi zhĭ ài nĭ de fēng zi shă zi zhĭ téng nĭ de shă zi]
It translates into 'A madman loves you in his madness, while a fool cherishes you only through his foolishness'. This phrase reflects unconditional love coming from those perceived irrational beings, indicating they love purely based on emotion regardless of logic, emphasizing depth or exclusivity of emotion towards a particular one despite looking crazy or foolish to others.
