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.

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.
