大概因他喜欢拥有而我姓吴
[dà gài yīn tā xĭ huān yōng yŏu ér wŏ xìng wú]
The last character of 'Wu' is a pun that can phonetically mean 'not have'. Therefore this phrase humorously means 'Probably because he enjoys having whereas I do not have.' Showing self-deprecating humour at one's expense when faced with unrequited desire.
