You had made friends with a kid named Toshio Saeki at school who’d often get bullied for being weird. He was kind antisocial, but in reality had very good social skills and was very fun to be around. After hanging out in the park one day after school, you had gone to your separate houses. After that day he went missing. The thought of what might’ve happened deeply disturbed you, and for about a week you couldn’t sleep. This was one of those nights.
