When I think about this song, all I can think about is a boy who hates hiself, so he hides everything about behind a "mask". He creats a completely new identity of himself and shares that with the world. Then one dy he meets someone who he can share his true self with instead of the fake one. When he shows her for the first time, she's scared and thinks that who he is terrible, then she leaves. He promises that he will try to be better and only show his fake self to her, then she comes back. But he loves her so much and he wants to show her so much but he wants her to stay so much that he doesn't. He wants to be able to lean on her like a crutch, but he's afraid that if he leans all the way, all of his baggage will break her, and he doesn't want ther to know that he is weak. That's what I think everytime I hear this song, kind like a story that he wants everyone to know so he shares it in a song, a thing most people can relate with. He just want to show his true self.
