Junichirou Kagami is a brilliant but eccentric young physicist who’s also a devoted anime fan. He suffers from "YD," a self-diagnosed condition that makes him only capable of doing what he truly wants-leading him to abandon his scientific career in favor of running an anime blog. When his sister Suzune, fed up with his shut-in lifestyle, pushes him to accept a job as a high school physics teacher, Junichirou reluctantly agrees. Though he has no interest in teaching the usual lessons, he might still have something meaningful to share with his students-not just about science, but about life itself. As he guides his class, Junichirou helps them learn to accept themselves and others, form genuine friendships, and find fulfillment by pursuing what they truly desire.
