毁我爱她少年你真棒无他不爱菇凉你真棒
[huĭ wŏ ài tā shăo nián nĭ zhēn bàng wú tā bù ài gū liáng nĭ zhēn bàng]
'Praise directed ironically for ruining my young self in loving her and praise for a girl who does not love anyone else truly'; this expresses irony and possibly pain from failed relationships or unreturned affections.
