Peri and Kon: Where is Paradise?

Peri and Kon are orphans pretending their parents are alive until they’re both over 18. Peri forges notes and pretends her parents have attended school events, and teachers seem to “remember” them.. Kon doesn’t participate in after-school activities, instead taunting neighbor Brenda, an animal hoarder. Peri, concerned that Kon is becoming maladjusted, decides to go on vacation to Nicaragua with him. Will they find a way to move on?
