始终不懂你所坚持的爱
[shĭ zhōng bù dŏng nĭ suŏ jiān chí de ài]
It means 'I never understand the love you insist on.' This might be used to express frustration in communication with a loved one, where the owner can't fathom the other's thoughts about romance or even can't fully understand his or her own pursuit in relationships, which makes everything hard to figure out.
