傻瓜还爱着笨蛋
[shă guā hái ài zhe bèn dàn]
The nickname 'Silly person still loves the fool' implies a situation where one individual (fool) foolishly stays infatuated with another (silly one). This is commonly used by people to describe their own state of naivety in love and acceptance of this seemingly nonsensical attachment. Such individuals often self-deprecate as a way to express their affection.
