You're her

People always come up to her and say 'you're her,you're the one that sees all' she's always confused but she's gotten used to it.
One day in her college class she sees her teacher start to change forms, she stands up and gasps. She thinks she's going crazy. It's been about 5 years and everyone she's seen changes forms, but only she can see. Then one day comes and she sees this guy, he doesn't change forms, he just looks normal. Why can't she see him change? Who is he? It's almost unreal seeing someone not morph, it's relaxing, and I haven't been relaxed in a long while
She spend most of her time at the library, working, reading. Books were easy, they didn't morph, they were just words on a piece of paper.
She'd tried looking up why she saw what she did but nothing came up.
Did he know what was happening? Could he help her?
