Taihei comes home to a complete stranger: Umaru’s public face. She’s cleaned the apartment and hidden her games to be able to invite her classmate and neighbor, Ebina, over.

Taihei and Umaru experiment with free time and personal space in their little apartment, and playing “The Game of Life” hits too close to home for them all.

It’s Valentine’s Day! Kirie burns cookies, Ebina attempts to make chocolate, and Umaru continues to offload food prep to Taihei.

Taihei invites his coworkers over for dinner after work, and one of them, Alex, catches Umaru's attention. Why does this guy seem so familiar, and what's his deal with anime?

While visiting Umaru, Kirie’s secret aspiration is found out! Will Umaru’s encouragement be enough to help Kirie overcome her self-doubt?

Kirie devises a new plan to bring Ebina and Taihei closer. However, Taihei might have a couple to many little sisters fighting for his attention already.
