Well you have that " one thing". The one that everyone says that's "what makes you beautiful". But the guy is "torn" cuz he's "taken" but he loves "everything about you". He stays " up all night" thinking " I should've kissed you". You " stole his heart", but your makin " the same mistakes" cuz you r so shy and you can't see that " it's gotta be you". He's thinking " I wish" she'd realize how beautiful she is and how much " I want" her. You are always thinking about all the " moments" you spent with him. You know that he knows this love can be " more than this" but everyone keeps sayin " na na na". But everyone looks at you and they're taken to " another world".
what i think the line means is i think it means that just because you are different doesnt make you ugly so bwhat i am trying to say isn that when you look at yourself you may think you are different which makes you ugly(i dont think your ugly).but everyone else they know that just because you are different doesnt make you ugly it makes you pretty and unique.this is coming frm me and this is what i think.
