Sneaky was a clever person, though it didn't show on the surface; he loved playing video games and was always curious about the future. He constantly wondered what lay ahead—what kind of changes the future might bring. One morning, Sneaky woke up and went to school as usual, only to be hit on the head by a ball in the playground; it actually hurt, but he didn't want to let it show. The same thing happened the next day, and the day after that—Sneaky felt he couldn't take it anymore, yet nothing changed. The following day, he tried taking a different route, but this time he fell; he was now certain that strange things were happening. Time passed—months went by—and Sneaky tried a new path every day; he finally realized he was trapped in a loop of time. He didn't know what to do, and time continued to unfold in that same way... until the Sneaky from the future arrived. So, that much time had actually passed; Sneaky was surprised to see himself. The older Sneaky saved him from that moment and took him just one day into the future. Sneaky was overjoyed that everything had been set right, yet he was confused. Years went by, and Sneaky entered university; he knew so much now—he was going to build a time machine! He succeeded in finishing the machine. Curious about his own childhood, he traveled back a few years and helped the younger Sneaky, who had become trapped in time; then, he understood the cycle of time... Suddenly, Sneaky woke up in bed. Had it all been a dream? Was everything fake? He was even dreaming within a dream; Sneaky was truly starting to lose his mind and couldn't make sense of anything. He left the house and saw the future...
I think it has to be a sneaky girl; I'm sorry. I wrote this story myself, but since my English isn't very good, I translated it. I am truly sorry; I hope this doesn't cause a problem.
