Seki-kun starts shining his desk during class. Amazed at the effect of his work, Yokoi-san finds herself being dragged into his want to shine more desks.

Seki creates an elaborate post office system for passing notes around the class; with many protocols that prevent Rumi from giving him a note of her own.

During art class, Seki plays a miniature-sized game of golf on his worn-out desk, whilst Rumi's classmate, Sakurako Gotō, misinterprets the interactions between Rumi and Seki as romantic gestures.

Seki studies a set of driving rules, takes a written driving test, and then makes a driving course on his desk for a remote-controlled car, which he takes very seriously.

During water safety lessons, Rumi once again becomes invested in the diligence of the robot family, becoming panicked when the child robot is thrown into the pool by Uzawa.

Whilst Rumi is off school with a cold, Goto observes Seki as he plays a game of paper sumo involving a robot opponent, assuming he had a fight with Rumi.

Seki puts on a blindfold and plays a game of fukuwarai, which soon evolves into a twisting story about family life.

Seki brings various pairs of glasses to see which pair looks the best on him.
