毕竟你喜欢离开而我姓刘
[bì jìng nĭ xĭ huān lí kāi ér wŏ xìng liú]
Translates roughly into 'After all, you like leaving and I’m Mr./Miss Liu'. Here the person may lament their own situation and surname while pointing out the other person's habit of distancing or leaving which could imply that they feel doomed to always stay or be left behind as their name does not change.
