Yamada no Gakkyuu Nisshi山田の学級日誌; Yamada's Class Diary

Yamada, a super serious girl, is the only female student in a previously all-males school. Not minding that she is called "boring," and "overly-serious," by those around her, she spends her days working hard to get a scholarship, for which she'll do anything. One day, she is told by her homeroom teacher that if she can get a truant classmate named Murata to go to school, he'll give her good marks and Yamada reluctantly agrees. When she heads to the game center Murata's at, standing before her is a frivolous boy who's surrounded by girls?!
