Synopsis
"That's right. Will you go out with me?"

Confessed to the beautiful girl. In order to get out of the daily life that tends to get entangled with Yankees, I went to Kyokogaoka Gakuen High School, a former young lady's school, and finally got her for the first time.

I thought that this would lead to a happy high school life that I had dreamed of- "I like Haru-kun. You want me to be yours forever, right?"

Why am I the first time ? Is she about to be killed on a date?

Keep an eye on the consequences of the shock. This is a story of two clumsy love and murder.
