The story takes place in the back hill of the school. The three of them were having a lot of fun. They thought it was a happy one-day trip to the back hill. Unexpectedly, they received a secret message from another world in the middle of the trip. In the middle of the night, the three of them met at the back of the school. But at this time, the back of the school... Was it still the paradise of green mountains and green waters of the past? Haha, that is already an enchantment table...
