Acatalepsy n.- incomprehensibleness, or the impossibility of comprehending or conceiving a thing.

There are some things even he,a genius,could never hope to understand.
Things far too complex,things not based on logic that he was so good at.

And among those bizaareness...she stands out from the thing that bothers him the most.

Her.

Tateyama Ayano.

There were things about her he could never give an definitive answer. Her cheerful attachment she had to her red scarf. Her goal of making a thousand paper cranes.

He could not understand...why she chose to befriend him among all people,why she sees a hero in place of the lonely, apathetic, genius boy.

She was a girl who,beneath the exterior,seems to hide more than meets the eye.

And even he could never find out what lies beneath her cheerful self.

He wanted too,but he was too afraid to talk about it.

Human emotions are not based on logic,and he was afraid of making mistakes.

So he never asked at all.

He kept up with his seemingly uncaring coldhearted personality,never raising the subject.

Even when she saw her cry at the classroom when she thought she was alone,he did not.

After all,he should not care about it at all.

Until the day...when he would come to regret it.

The girl full of complexities,has flown away to the wind and died ,leaving him made his heart heavy,grief showing on his usually annoyede expression.

He came to regret...how he never asked.
How he decided to let it pass,only to realize it would be too late in the end.

He could never find out...about those things that crossed his mind.
Why she was crying last time,and how it led to this event.

He came to regret...that even now he would never know.

The answer...will never be clear.
