Alex dropped in while Jenny was writing her essay in the library. After classes, if she didn’t go to the science room, she often went to the library to sit until evening to plan contents for the media channels – it was for the research team. The quiet space here made her more focused. Partly because she hated the sight of Charles surrounded by female members. He seemed nice to everyone.“Charles asked me why you left this morning,” Alex whispered to Jenny because they were not allowed to make noise in the library. There was also a time when he had spoken so loud. The librarian had got angry and had told him to go out.Jenny looked at Alex pulling out his iPad and his stylus to edit the sketch and suddenly felt a little strange. He didn’t like quiet places like libraries, especially after getting kicked out by the librarian. The over 6’ tall, smoky hair, and well-groomed style always made Alex stand out and be easily recognized.“Then what did you answer?” Jenny whispered back.Alex sh

Charles thought he understood what Alex meant yesterday.He stood in the corridor in front of the science room, looking down at the yard, where a girl with lavender hair was walking and talking with two other girls, perhaps about buying something. Jenny was always the type of person to give her all. Once she had her heart set on anything, she would spend every moment. In addition to managing the team’s media channels, applying for grants, and being in charge of selling apps on Scistore*, she was the one to attract more members to join the research team. There were times Charles saw her hanging out with the thugs-looking seniors in the university. It sounded a bit funny, but he thought she was like the brokers in Genright Harbor, where merchants gathered to trade in the old days. Genright was known as a happy and generous city because of its diversity of markets and diverse cultures. Immigrants were always welcomed, and they had many job opportunities for economic development.Anyways,

“I can't believe how crazy they are,” Jason exclaimed. He was following Jenny to the front door of the lab. “You're like VIPs now, completely different from us before.”“Because there are many expensive things that are easy to steal. Professor Keylor is a worried person,” Jenny said as she searched her bag for the key card and opened the door, not really in the mood to explain.“I think he should be worried about something else, like some crazy guys selling drugs in here,” he said.Then the door opened. In front of them was Charles, who was cleaning up broken glass pieces and liquid on the floor with a broom. It seemed like he just broke a test jar or something.“Hi, long time no see,” he said, smiling through his mask. He was surprised. “Jason, do you come here to play with me too?”“Yeah, I heard someone was holding a party, so I come and join!” Jason joked with a serious face.“Party? Yeah, that’s right. Come in here. There are free sulfuric acid cocktails,” Charles said. “Just kid

If they didn't go back, there will be “them” in another timeline going to Jenny and Anna. That wasn’t a joke. Before, while building the time machine, Alex had studied paradoxes. That was the possibility that might happen when he used the time machine to create a path through the fourth dimension – called a wormhole – to travel back in time. Not to mention there were other possibilities. For example, their mission was probably successful this time, but when they used the wormhole to go back here again, they would end up on another planet or go back to thousands of years ago.Or worse, the feedback would destroy the wormhole*. If so, he didn’t know what would happen.That’s what Alex thought when he pressed the “go” button.He felt a tremendous amount of energy sucking in them, the wind whistling in his ears like he was riding a roller coaster, but at a speed so fast it almost couldn’t be measured.Charles, look who’s crazier now, you or me?“Zap… zap…”After the sounds of the machine,
