So a lot of people are trying to guess what this song is about and so here is the answer to your guesses. When this boy was little he wasn't loved and so he didn't feel anything. As a result of this he wanted to feel something so he became violent. Proceeding to say that he feels something when he touches others. Meg and Dia said that they use the word monster because in the book this is based on you become a monster if you have no love in your life. Now hes wondering how he should feel. Then he abuses this girl and steals her virginity but realizes that this is hurting her when he thought it was love because he never knew what love was. And now everyone is talking about how Hannah had this kid and the kid hears all this and knows that he/she is Hannah's regrets. Now the boy kills himself after seeing that what he did wasn't love by bathing in kerosene and lighting it on fire which makes the bathtub full of glow flies (fire).
