菇凉你薄情如初少年你情深似海
[gū liáng nĭ bó qíng rú chū shăo nián nĭ qíng shēn sì hăi]
Expresses contrasting depths of feelings between two individuals—the girl appears cold and indifferent while the young man harbors deep-seated emotions that never changed, reminiscent of traditional narratives of unreciprocated love or dramatic romances.
