喜你成疾恋你成风
[xĭ nĭ chéng jí liàn nĭ chéng fēng]
The poetic expression of being obsessed to the level of being sick because of joy ("Sick With Love") while having emotions as intangible yet pervasive as the wind ("You've become my passion blowing like the wind") shows the extremes of infatuation and affection someone has towards another person.
