Last Bet

Around 4:30 pm on June 5th, a fourteen-year-old male student from a private junior high school fell from the school roof. He passed shortly after at the hospital he was transferred to. The police assumed it to have been an accident and closed the investigation. An unfortunate happening. Something no one had been planning or could have predicted. Is it okay to let this tragedy be filed as a mere accident? [Translated from NovelGame]
