High schooler Nina Yamada is serious, studious—and the only girl in her class at a formerly all-boys school. She doesn't exactly get along with her classmates, but she'll work her butt off for a good college recommendation no matter what! So one day, when her teacher asks her to get the truant Murata to come back to school, she puts aside her reservations and braves the local arcade...only to find Murata surrounded by girls waiting on him hand and foot! Can Nina get through to this absentee playboy, or will it prove to be the one thing her hard work won't help with?
