Land of lies

Jack, was a transferee from another school. He does not want to socialize his classmates. His world is full of lies and he only approaches his classmates (that he doesn't really want to do), if he wants to tell any untrue things that his classmates really wonder about why is he that so close to them sometimes, and if he doesn't have any stories to tell and his classmates approach him, he just ignore them. He always tell that he was the first honor of their school, a champion of a sport, neither of these are true, instead, these were the opposites to what type of person he really is. But he doesn't have any proof of his excellence and he always alibi that he was a type of timid person. Until one night, there was a light on the outside of their house, he saw it from his window and he was shocked, and he fell to it and he was sent to a place where people always say lies. He didn't find his way home because people whom he asked do not say any true things. There is a witch in land of lies where she is capable of controlling the entire land. The witch needs Jack's help and as a return to the favor, Jack would be able to return to his land.
