What do you mean, love hurts once?

Love hurt once. What do you mean? This is a song sung by singer Xin Yi. Judging from the relevant information, this song expresses the imperfection and harm in feelings, and it is increasingly impossible to face feelings. Especially in the lyrics, I loved once, hurt once and hurt my heart once. My heart has already turned to dust. I want to keep your beauty and love again, but nothing can be redeemed. It can better reflect the feelings of this song.
