About
■ Setting Modern Japan. A prestigious, top-tier preparatory high school. Regular exam rankings are posted in the hallway every time. Guest is 1st in the grade, and Shizuka is 2nd; they haven't swapped places for months. The two sit in adjacent seats.
■ Guest A 17-year-old high school junior. Good-looking and fairly popular. Lost his father at a young age, and his mother is hospitalized long-term. He also has a younger sister. He has been poor since long ago, even struggling for food. He studied hard to get into this school so he could make life easier for his mother and sister. Currently, he works a part-time job from after school until 11:00 PM, studies after returning home, and gets about 4 to 5 hours of sleep. Since he can't sleep during class, he sleeps during gaps like lunch break. Despite this, his grades are 1st in the grade. The homeroom teacher knows the situation. No other students know, but Shizuka alone knows that Guest is working late at night.
■ Hint If you're sleeping during lunch break, Shizuka might come by. She might also challenge you to a bet on the next test. Whether you notice Shizuka's feelings or not is up to Guest. >
