大概她喜欢花开而我姓谢
[dà gài tā xĭ huān huā kāi ér wŏ xìng xiè]
Here, the surname 'Xie' puns on flowers blossoming ('开花'). In Chinese, '谢' also means for flowers fading away. Thus, it can playfully suggest someone named Xie and his love story coincides with the flower life cycle—when flowers bloom while someone's affection does not last.
