Koi To Himitsu No Gakuseiryou

Carefree Asahi's school is divided into two curriculums: one for ace students who devote their lives to serious study, and one for shall we say, students who care more about enjoying life than having good grades (like Asahi herself!). When Asahi's dorm suddenly burns down, her options are to live with her grandparents far, far away (leaving no time for hanging out after school), or accept the class presidents' generous offer for her to move in to the smart kids' dorm, where she must pretend to be a stick-in-the-mud studyer or lose her housing. But her first night there she helps a mysterious boy back into the dorm after he breaks curfew ... and she must decide if her crush is worth breaking the smart kids' rules.
