Synopsis
Run away. To protect only one love.

Writing on a certain SNS has become a hot topic. One high school student, Otohiko Omura, dominated and blackmailed several junior high school students. That amount, a total of 30 million yen. And tonight, he finally killed three junior high school students.

"But I know it's the worst lie, because Omura Otohiko is my name."

The only clue I got in the worst overnight getaway. That is the existence of a junior high school girl named Yoto Enokida. When a boy and a girl living in a broken world meet.
