She was different.

Her multiple obsessions of repeating the same thing over and over. Her absolute horror of being touched. Her tendency to keep to herself and not speak. Her sky high grades which always topped the list. Her random tantrums which could suddenly explode. 

Yes, she was different.

But Tiffany saw through that. She saw the fragile girl trying to fit into the cruel reality which she did not understand. She saw her heart, even though her ability to express herself was sorely lacking. She saw it all.

And she knew one thing.

She was determined to break into her world.

Taeyeon's autistic world.
