不善表达的我不懂挽留的你
[bù shàn biăo dá de wŏ bù dŏng wăn liú de nĭ]
Translating into 'the not-good-at-expressing-me doesn't understand the you who cannot let go,' which expresses the difficulty and helplessness in communication between two individuals, one who can't properly express feelings, and the other who struggles to say goodbye or leave.
