西瓜熟了夏天走了他丢了
[xī guā shú le xià tiān zŏu le tā diū le]
This name conveys a sense of loss and nostalgia, reflecting that as summer ended and the watermelon ripened (often signifying a sweet memory or period), someone important left. Watermelons being ripe in summer are a seasonal connection suggesting fleeting relationships and moments.
