Mario and Luigi thought they were just attending high school. Nothing special, nothing different, the same boring school. However, as they continue through the year they develop new crushes, meet some new friends, and have an awesome high school adventure! With love at every corner, and unexpected events, this won't be a normal school year for the Mario Bros!

This story is about the life of Bowser before he became evil. Before the events of the original Super Mario Bros., he fell in love with a beautiful white-haired girl named Rosaria, who deeply cared about him, despite his "imfamous montrosity". Throughout the story, the Koopa King is doing what it takes to be a good guy, if he can avoid a certain prophecy.
