大概是你喜欢走而我姓刘
[dà gài shì nĭ xĭ huān zŏu ér wŏ xìng liú]
'Probably you like to walk away and I'm Mr./Miss Li.' Using this somewhat cryptic reference could mean that while one person is always leaving or moving on, 'Li' sounds similar to 'stay' ('li') in Chinese, highlighting their different attitudes or choices.
