Kouichi Itoda.
He was an introverted type.
In spite of this he had a girlfriend from
the same class, who was beautiful, kind,
and rather out of his league.
Kouichi worried about this a lot.

One day an incident happened near the school.
A package arrived from one of her male friends.
Kouichi was suspicious and opened it...
That was the night it all went to hell.

His false happiness was obliterated.
Faced with a choice.
