她说无所谓
Tā shuō wúsuǒwèi
She says it doesn't matter
无所谓 is a fixed four-character phrase meaning 'it doesn't matter / whatever.' Here it functions as reported speech folded straight into the sentence, with no quotation marks or 说...的话 framing needed — a normal feature of Chinese indirect speech. The phrase becomes the song's ironic refrain: insisting something doesn't matter is usually a sign that it does.
