This song is about a speaker addressing somebody else. The song doesn't make it clear whether it's a significant other or not. It is clear that both people have faults that need to be fixed, and a history that the speaker insists that they need to bury.
The speaker seems to comfort themselves by reassuring themselves that they're "Nothing like" the other person, but the song later reveals that this is just a pun. The speaker admits that they are "nothing," just like the person they're addressing.
