掐指一算你命里有我
[qiā zhĭ yī suàn nĭ mìng lĭ yŏu wŏ]
This means something like 'By deduction I am destined in your fate.' This type of phrase stems from the idea in Chinese tradition that one's destiny or future could be calculated through various practices (here represented by finger-calculations). A more colloquial interpretation may suggest a fateful romance between individuals.
