Dark parallel trap

Owen is a normal boy with a normal family. All of that changed one day. The bell rang and his school is somehow different. The combination lock on his locker showed the number placed in a counter clockwise fashion. The school cheers as a boy that was suspended was being chased by alligators at a pool. Though the thing that makes this school very different from the school that he knew was that people at this school have a saying "Being bad is good". Though Owen somehow shifts into this unfamiliar version of this school with the sound of the school bell. Also, somebody is after him. This person looks exactly like Owen. Although he seems a bit bad. Can Owen avoid his double? Or will he be forced to live in the unfamiliar version of his world for good?
