你明知我心已碎
[nĭ míng zhī wŏ xīn yĭ suì]
'Nǐ míng zhī wǒ xīn yǐ suì,' simply put as 'You know my heart was broken.' This phrase reflects a sentiment wherein the individual admits to experiencing significant emotional damage caused probably during romantic engagements where partners have prior knowledge of said damages occurring already between them two, hinting at unreciprocated emotions or misunderstandings.
