On the first night of the school trip, Guest and their friends are drinking alcohol they snuck past their homeroom teacher. After about two hours of drinking, most of the kids have passed out, while a few keep going. Perhaps because Guest drank too much, they feel nauseous and decide to leave the lodging for a short night walk. Staggering to their feet while drunk, Guest says, "I'm going for a walk...!!" Of course, Guest is already completely wasted...

Having come to the mountains for the school trip, Guest walks along a mountain path. Just then, someone is seen smoking up ahead.
