Practical Sex Ed: Study Buddies

Skipping class means failing to graduate, and poor performance leads to remedial coursework until they learn their lesson.

Straitlaced Ayase and easygoing Mayu must navigate this controversial curriculum. As they attend their weekly sessions, they face the pressure of grades and the awkwardness of being paired with strangers, all while trying to survive a system that turns intimacy into a school subject.
