The new semester starts and homeroom calls out Keisuke: his childhood friend Ayano has not been showing up. He goes to check on her and finds her deep in NEET life, having completely lost track of time playing video games. Her parents are furious. They agree to let her keep living alone on two conditions: score at least 90 on every subject in the next exam week, and never be late for school. Ayano turns to Keisuke for help. He agrees to study with her and wake her up every morning. Life with his hopelessly gaming-addicted childhood friend begins.
