Cobain is a talented illustrator who expresses his inner world by drawing and painting. Suffering from social anxiety, he chooses to stay home and listen to music to pass the time. If he needs to go out, he wears a raincoat, which acts as a protective amulet for him.

Rejected by society due to their inability to accept his strange behaviour, Cobain dropped out of school, opened his own studio, and cut off contact with his family.

One New Year's Eve, he fled to a shop in order to avoid his friend who was trying to force NYE plans on him. Instead, he was taken hostage by a criminal, and used to hijack a bus. Trapped with so many people in an enclosed space, will Cobain further retreat into himself, or face this strange, exciting, and terrifying journey?
