Is it wrong to be attracted to a flaw?

So... i've been watching this girl with tourettes for a while. I think she is adorable because of it.
Don't misunderstand me, though. I am aware that she is not having the time of her life with such a disability.
But at the same time i can't help but feel attracted to this quality... this flaw... in her mind and personality.

So my question is if this is wrong? Is it wrong to feel this way?
