The song "Come Clean" by H.E.A.T is about the lingering feelings and thoughts the narrator has for someone they used to be involved with. It explores the struggle of trying to move on and forget about that person, but constantly finding themselves still thinking about them. The lyrics mention how they both moved on to other people, indicating that they have tried to find new love and relationships. However, despite this, the narrator admits that they never stopped thinking about the girl they used to be with. It's clear that they still have strong feelings for her, which they describe as obscene because it seems inappropriate or wrong to keep dreaming about her. The song also reflects on the fact that they both made a conscious decision to leave each other and move on, but the memories of their time together still weigh heavily on the narrator. They express doubt about whether the changes that happened after their breakup can ever be erased. The line "We'll never be strangers can't help this fall from grace" suggests that they still have a connection and can't fully let go of the past. Overall, "Come Clean" is a confession of the narrator's ongoing love and longing for someone they've tried to forget. It acknowledges the difficulty of moving on and the internal conflict that arises between their current relationships and their persistent thoughts about the person they used to be with.
