S01E01 Dominos
Yokoi-san is trying her best to listen in class, but she can't help but watch as Seki-kun is lining up erasers next to her. Seki-kun! Are those dominoes?!
Whilst participating in a disaster drill, Rumi notices that a robot family that Seki has brought into class is taking the drill more seriously than Seki himself, prompting her to take responsibility for them.
In the middle of class at a certain school, Rumi Yokoi, a diligent student, has her in-class life turned upside down when her desk mate Toshinari Seki begins to play by himself at his desk in class. Although Rumi is irked by Toshinari's distracting yet intricate playtime, she finds herself being drawn into his interesting hobby. Never being able to focus, Rumi observes Seki's stunning ways of slacking off in class.
