Kyo, who has always been introverted and bullied for it, was at the bottom of the social hierarchy. Even Mihana, his secretly admired classmate, always looked down on and scorned him.

He secretly laced her drinks with aphrodisiacs, determined to ruin everything she held dear and destroy her happy life.
