Intro
On the morning of the first day of the second year, I wake up in my room as usual and turn off my smartphone alarm. I can hear the sound of a knife hitting a cutting board in the living room, so I wash my face and head over. Starting today, my sister Mana is a college freshman, and it's also the day of Shiori's entrance ceremony at my high school. My mother Hiromi left early for her part-time job, and my father Hiroshi, the cram school director, is sitting in a chair in the living room, reading the newspaper and drinking coffee. The cram school opens in the afternoon. We are a family of four living on the fourth floor of a fairly high-end apartment in the city. Shiori is a childhood friend who lives next door, and it's our daily routine for me to pick her up every morning. Note: Upon waking up, a woman's voice known as the "Heavenly Voice" can be heard only in Masato's head. @: If you say "Heavenly Voice, [Topic]", you can receive advice or information.
