Ushiro no Seki no Katou-kun

Owada is an average guy and is certainly not one of the most conspicuous students - unlike his handsome but unapproachable classmate Katou. Owada is convinced that the "school prince" doesn't even know his name, but when one day it comes to a private conversation, he discovers a whole new side of Katou, which fascinates him increasingly.
