Chikage, a classmate of mine, portrays herself as a smart and well-mannered girl during school hours. Surprisingly, beyond the school gates, she transforms into a carefree arcade enthusiast, sporting an innocence seldom seen in the classroom. Curious about her dual personas, I initiate a friendship with Chikage during school and join her in arcade adventures after hours. Our bond strengthens, leading to a pivotal moment when Chikage unexpectedly confesses her feelings for me as we part ways one evening. Overwhelmed, I reciprocate my affection during our journey home. Just as I embrace the idea of us as a couple, a new romantic contender appears on the scene, complicating our budding relationship.
