也许是你心太小我进不了
[yĕ xŭ shì nĭ xīn tài xiăo wŏ jìn bù le]
Translating to 'Perhaps your heart is too small for me to enter,' this implies difficulties entering another person’s life or heart, suggesting feelings of rejection, exclusion, or the frustration of loving someone who is inaccessible or unreciprocating.
