For as long as she's been aware, the heroine, without a single relative, lived under care of the state. Both of her parents' faces were unknown to her.
In front of this heroine, a young boy appeared.
The young boy's name was "Hikaru". It appeared that he was the heroine's twin brother, separated at birth. He had a proposal for the heroine.
"Could you go to school in my place?"
The heroine was shocked by this crazy suggestion.
Furthermore this was an all-boys school. The only high school in this prefecture for delinquents.
