这个夏天没了西瓜也没了你
[zhè gè xià tiān méi le xī guā yĕ méi le nĭ]
'Zhe ge xia tian me le xigua ye me le ni' can be understood as 'This summer without watermelon and you', indicating two losses - one is the pleasure like having sweet cold watermelons in hot weather, while another loss is of a loved one. The user may wish someone (or themselves) were there last summertime sharing good moments with the other person, but that moment cannot be reclaimed anymore because the time has passed, and so has the beloved one.
