扰了纯真的情乱了纯真的心
[răo le chún zhēn de qíng luàn le chún zhēn de xīn]
This expresses "Disturbed Innocence" in a more poetic manner, describing the sentiment of innocent love being disturbed and pure-hearted feelings being disrupted. There's often nostalgia and pain associated with the loss of innocence and purity of feeling during youth.
