Synopsis
July 22, 2015 12:20. Tata, a mysterious woman who claims to be a witch from another world, "Hey, Yu-kun. I'm you--"

I stopped at the voice I heard for the first time. The way back from school. A junior high school ground and a bookstore in front of the station. Then, in the vacant lot where the white cat sleeps, Yuki Shiina, a mysterious girl who knows me for some reason, always called out like that.

Laugh, cry, get angry, hold hands.

Many times, we make promises that do not exist anywhere, with memories that disappear.

So I didn't know anything.

The value of Yuki's smile and the meaning of tears shed. Even one thought that was put into many "Nice to meet you".

――This is a story of encounter and farewell that is cruel and painful and captures your heart.
