我未尝试过你的甜蜜我不曾体会你的温柔
[wŏ wèi cháng shì guò nĭ de tián mì wŏ bù céng tĭ huì nĭ de wēn róu]
Expressing unreciprocated love or missed opportunities, this implies that one hasn't experienced the sweetness or tenderness the other might have offered, possibly regretting never having been in love with them.
