对于你生命唯一至于你拼命珍惜
[duì yú nĭ shēng mìng wéi yī zhì yú nĭ pīn mìng zhēn xī]
For you alone, my only one, I cherish desperately – it means that you are the only thing/person in their life that they have desperately cherished, expressing a profound depth of value or love for a specific person or something.
