ABBERATION

(n.) Aberration- something that differs from the norm.

She was his ABERRATION.
Tom could not get the ambitious but enigmatic Ravenclaw out of his wretched head. He swore that he would find her in every universe, every life and every reality because she was his and only his.

If he had just known that he was a milestone to someone else's story, he would have tried harder to make his own story with her.

He would always find her again.

"A sky full of stars and he was staring solely at her"
