Junichirou Kagami is a young published physicist, a genius, and a hopeless otaku. Suffering from YD, a self-diagnosed condition that compels him to only do what he "Yearns to Do," Junichirou abandons his scientific career to maintain and improve his anime blog. However, when he is hired as a high school physics teacher, his sister Suzune, no longer willing to tolerate his NEET lifestyle, forces him to accept the position. Although Junichirou lacks motivation to teach the standard curriculum, he may still have something of value to offer his students beyond academics. With his class in tow, Junichirou embarks on an unlikely journey filled with life lessons, such as accepting others, how to make lasting friends, and what it means to live a better life by doing what you yearn to do.
