爱你成病想你成疯
[ài nĭ chéng bìng xiăng nĭ chéng fēng]
Expressing a deep emotional entanglement, the meaning here is along the lines of 'Love turns to sickness; thoughts of you lead to madness.' It poetically illustrates an obsessive level of love and desire, indicating intense emotions that go beyond healthy affection towards someone, emphasizing the power and impact of passion.
