我姓刘却没有留住你
[wŏ xìng liú què méi yŏu liú zhù nĭ]
The owner uses their surname 'Liu' (as in English names, Liu is not that common) to imply a pun in Chinese culture where leaving (liu - same pronunciation as 刘 but different character meaning stay) connects with this sentiment that even I am 'Liu', you could not be kept by me which indicates that the person he cares cannot stay in his life.
