Shocked and Lovestruck

Kirie Motoba is a petite girl who has a tendency to be violent at times when embarrassed. For quite a while now, she's had a huge crush on Umaru Doma, a seemingly perfect, popular high school girl who's kind to everyone. Kirie is viewed by her classmates as scary and unapproachable, so she really doesn't have any friends and is quite lonely. This makes it so that her love interest doesn't notice her for quite a while. What happens when they end up becoming friends, and Kirie finds out Umaru's true identity?
