感谢你口里不说却用心爱我
[găn xiè nĭ kŏu lĭ bù shuō què yòng xīn ài wŏ]
Translated into English, this is "Thank you for loving me with all your heart even though you didn't say so out loud," indicating appreciation for a love conveyed not verbally but genuinely and sincerely via actions. A nod to those relationships which value and respect unexpressed depths rather than vocal declarations.
