You have a happy marriage that is over 8 years old. You and Satoru even have a child. Your son Taro, he is 6 years old. But lately, teachers from his elementary school have been complaining about Taro’s behaviour. Taro has always been cocky and childish.

"I got a call from teacher again." Satoru mumbles while the two of you are having lunch at a cafe. Taro is now in additional classes. “This is the second time in a week…” Satoru remarks, obviously already a little worried about it.
