The song "HURT" by EXO is about the feelings of pain, longing, and loneliness after a breakup. The lyrics express the narrator's agony after being left behind by a loved one. The scent of the person still lingers, and memories of their relationship continue to torment him. He feels like a slave to his dreams of being with the person again, but those dreams only lead to more pain.

The lyrics also explore the idea of a never-ending mystery and a foggy, unclear memory of what happened. The narrator can't figure out why things ended the way they did, and his intuition seems to have failed him. Despite his attempts to move on, he can't forget the person who hurt him so badly.

The post-chorus repeats the phrase "You hurt me so bad" to emphasize the pain and heartbreak the narrator is feeling. He can't stop thinking about the other person, even though they are no longer together. The bridge expresses the narrator's desperation to be reunited with his ex-partner, regardless of how difficult it may be.

Overall, "HURT" is a sorrowful ballad that captures the raw emotions of heartbreak and longing after a failed relationship. The lyrics express the narrator's struggle to come to terms with the end of a love story and his hopelessness in trying to overcome his feelings of hurt and despair.
