Note: There's no magic in this novel. This was previously in the Realistic Fiction genre but it's not included in the choices. So I picked the closest one to it.
Onoda Ruki is just your ordinary high school student. He strived for being the Classmate A who's unimportant to the story.
Despite being the Classmate A. Onoda has a secret desire which he always had ever since young and that was to steal each and every girl from their guy.
