i thought the same thing as everyone else and i loved it, it's so perfect for me, but then a friend of mine told me it was misinterpreted, that she's with her boyfriend and she cant fall in love with him? we got in like an hour long debate about it haha

i was wondering if anyone else had heard this meaning?
