是你不懂并非我变
[shì nĭ bù dŏng bìng fēi wŏ biàn]
Meaning 'You Don't Understand, It's Not That I've Changed', indicates defensiveness while expressing unreciprocated feelings. There's underlying frustration conveyed here: despite misunderstandings occurring around personal change, there hasn't actually been any real transformation on their part; it criticizes the miscomprehension caused by other people rather than themselves changing.
