Minami Yuuri, now in her second year at Seitei Gakuen, an elite Tokyo academy running from kindergarten through college, finally moves up from middle school to the job she wanted: teaching grammar to high schoolers. Her assignment turns out to be Class 3-E, better known as Class X, a notorious group of seniors with poor study habits. Every teacher before her reportedly retired from ulcers or nervous breakdowns. Minami has to reach these students, including the six class leaders called the B6, and get them into college. The three-episode comedy and romance OVA is adapted from a dating simulation game aimed at female players.
