多情恰似有情无情胜过人心
[duō qíng qià sì yŏu qíng wú qíng shèng guò rén xīn]
It means that being deeply in love may resemble true feelings, yet sometimes a seeming lack of affection can outstrip genuine human nature. The depth and complexity of emotions often exceed simple judgment as people's heart might be filled with complicated sentiments and intentions which surpass straightforward comprehension.
