The meaning of life, the value of existence, may seem to be mysterious, but they are actually quite easy to understand.

- When you are needed by others

- When you need others

- When the people around you would be sad because of your disappearance

- When you feel sad because the disappearance of the people around you

In all of these situations, you will truly feel what the meaning of life is, what the value of existence is.

That is, to be loved by others.

This is a story about "need" and "existence".

-----------------------------

Nana is sitting on the railing of the rooftop, shaking her delicate ankles, her elegant white dress is swaying in the wind. The morning sun harshly shines on the pale purple flowers on her hairband, desperately tries to evaporate the last bit of moisture from its petals. As the corners of Nana's mouth twitched, she faintly let out a word -

"... High..."

Actually, Nana didn't know why she came alone to such a dangerous rooftop.

Perhaps it was because no one else to accompany her...

In the past, there was always one person who would accompany her.

That was Nana's older brother, her only relative.

A worthless person with no value.

A worthless person with nothing else to do but lying in bed all day long.

A worthless person that always telling Nana fairy tales with a slight smile.

A worthless person that sometimes would accompany Nana to the rooftop to watch the sky when he felt better.

Yes, Nana's brother was a useless person who could only rely on Nana to sell flowers for their living, and threw all the money to the hospital.

Nana has always thought that her brother is a worthless person with no value in his life.

If she had to say something good about him, he only had some value when he read stories for Nana.

He only had some value when he patted Nana's head and said, "Good job". It was only valuable

He only had some value when he put a flower on Nana and praised her for being cute.

And then, that brother abandoned even this tiny bit of value that proved his existence.

That worthless person died.

Well, a worthless person with no value in his life shouldn't have lived for such a long time anyway.

And... What about Nana?

Where is the meaning of her own existence?

The breeze from the rooftop gently moved Nana's skirt.

Right, Nana's meaning of existence is to take care of her critically ill brother...

But now that her brother is dead, then... just find a replacement, a new value of existence, a new meaning of life.

Well, her brother said she looked pretty with flowers.

Nana spread her fingers and saw a faint purple flower swaying in the wind between her fingers. The center of gravity of her body gradually rose with the her movement -

However, this time, Nana didn't bring it back down...
