seniors of class 5

a walk down memory lane of school memories filled with studying and bullying. after graduation, each student who was a senior of class 5 receives a message to participate in an alumni reunion. no one knows who sent the message. a reward of $10,000 and the location is an abandoned island. although there were some suspicious parts to the message, everyone participates, thinking that it was a joke. in this event, everyone relives and faces their past self which they had buried for so long.
