Chikage is a beautiful girl in my class who is smart and well-behaved. She is my rival in school, but after school, she has another face. After school, she plays in the arcade with an innocent smile that would be unimaginable in class. I try to make friends with Chikage on campus and play with her after school in order to get to know her better at both places. We grow closer to each other, until finally… a heartwarming triangular love comedy begins! (Source: Kadokawa, translated)
