等待你说等待花会开明白但是你没有坦白
[dĕng dài nĭ shuō dĕng dài huā huì kāi míng bái dàn shì nĭ méi yŏu tăn bái]
It translates roughly into: 'Waiting for you to speak, waiting like blooming flowers until I understand. However, you never confessed openly'. The person probably went through a period of anticipation and expectation towards a loved one or crush but got disappointed in the end because no confession came about.
